Explosive Doors

Description:

Before I begin, I must stress that even if you follow these steps closely, it's sometimes rather hard to reproduce, as it seems to also rely on another number of subtle conditions for it to occur. I am also inclined to believe that this report is not as comprehensive as I wish it were, as doors seem to explode outside the listed conditions, and regardless of whether they are vertical or horizontal. I do have to emphasize, however, that doors in general, both stone and wooden, have a chance of spontaneously collapsing, and this post serves as a request for more thorough testing from more competent testers than me.

---

- Whenever you place a horizontal door hanging from the edge of something (wall, cliff, etc.) with no backwalls or nothing to support it, there's a (very?) small chance it will explode without leaving a wooden backwall if you interact with it immediately after you place it (stepping/standing/jumping on it, or simply opening it). It also seems to be more prone to breaking suddenly if you're swinging your pickaxe at another block nearby, as long as your still within reach of the door.
- Whenever you place aditional blocks beside a horizontal door, and which are ONLY suspended by said door (for example, a platform made of wooden blocks), there is very good chance these blocks will collapse AFTER you unpack a building on said platform. There's a small chance that this will not immediately occur, but instead until you open the door. After a while, it seems to correct itself. However, should you place a wooden backwall (as support) beneath the wooden block that connects with the door and then destroy it, the platform has a chance collapsing. Worth noting is that the occurance seems to vary on whether you destroy the backwall while the door supporting the platform is open or closed.
- If you move upwards fast enough (works easier with a ladder) while placing a door, you will be shown to be behind a closed door instead of an open one.
- While the previous bug is in effect, if you place a door 2 spaces upwards and then proceed to break it, it will destroy the adjacent wooden backwall and ladder, and cause enough collapse damage to break the door that you're currently behind.

I do believe this also happens with a vertical door, as I've also had stone walls inexplicably collapse on people randomly when opening stone doors as I was placing blocks that were supported on said doors. However, I haven't tried purposefully recreating it myself.

Steps to reproduce:

The following steps comprehend the FIRST two bullet points from the previous section.

1.- Place a door on the edge of a wall or cliff.
2.- Interact with it immediately afterwords.
2a.- IF it hasn't been destroyed yet, proceed to step 3. ELSE, return to step 1.
3.- Create a platform made out of stone or wooden blocks (at least 5 blocks long), hanging only from the door without any other kind of support.
4.- Interact with the door immediately afterwords.
4a.- IF the platform hasn't collapsed, proceed to step 5. ELSE, return to step 1.
5.- Deploy a building on top of the building.
5a.- IF the platform hasn't collapsed after the building was deployed, proceed to step 6. ELSE, return to step 1.
6.- Open the door suspending the platform WITH a building on top.
6a.- IF the platform hasn't collapsed, proceed to step 7. ELSE, return to step 1.
7.- Place ONE stone or wooden backwall as support beneath the platform.
8.- While the door is CLOSED, destroy it.
8a.- IF the platform hasn't collapsed after destroying this support with the door CLOSED, proceed to step 9. ELSE, return to step 1.
9.- Place another backwall as support in the same place as the previous one, and while the door is OPEN, destroy it.
9a.- IF the platform hasn't collapsed after destroying this support with the door OPEN, proceed to step 10. ELSE, return to step 1.
10.- ...?
11.- Profit.

The following steps comprehend the LAST two bullet points from the previous section.

1.- Place 3-4 ladders on top of each other.
2.- Place backwalls behind said ladders.
3.- While travelling upwards, place a door above you, anticipating a spot you'll step into as the door is being placed.
3a.- IF you're behind the door (it MUST be shown as a CLOSED door), proceed to step 4. ELSE, destroy the door and return to step 3.
4.- While being behind a CLOSED door, place another door 2-3 spaces above you WITHOUT moving from your spot.
5.- Destroy the door you just placed.

Screenshots/Videos:

I'll edit this shortly to include some relevant screenshots.

EDIT: I believe I might have accidentally deleted my screenshots. All I have left are worthless thumbnails. I am not sure if I will be able to recreate it myself, but I do hope that my verbal report suffices. If needed be, I can try and take snapshots again.

 

I might have completely misinterpreted the pattern I used as basis for this report, since I disregarded another factor that I believed was innocuous at the time: ladders.

After being informed by several other people ingame that these currently count as empty space, and effectively render whatever support backwalls provided void, I realized that the scenarios I was tinkering around offline all involved building a moderately high tower. All which relied on ladders (not as support, but simply to aid in construction).

I'm most certain that ladders are the ones at fault here, but not entirely sure. I've been building more cautiously now, keeping away ladders from any kind of walls, and nothing seems to be collapsing now. I will continue to observe, nonetheless.

 

I've actually been experiencing this as well; this also affects bridges and the like; they just loose support and fall as if there were no walls or anything holding them up, this happens with or without ladders.
