Windows [1215] Knight/Builder/Archer blob spawning after switching class before dying

Category:
Both?
Operating system:
Windows 7
Build number:
1215
Description:
Basically if you switch your class with the class shops before you die from falling, it will leave a knight/builder/archer blob spawned there. When they spawn, they have no health, because when you hit it with your pick or stun it in anyway (even if you're on the same team) it will die. There isn't really a way to abuse the blob spawning other than allowing the builder to hold mats or maybe having one of 'em hold a flag. You can put them in doors and make them hold the door open. After you feed the blob he won't die from your teammates, and you can hit it with your pick (without the blob taking damage this time) and it will spam emotes.
Steps to reproduce:
1. Make a tower tall enough to die from fall damage.
2. Setup Knight/Builder/Archer shops below it.
3. Jump off the top and tap "e" right before you hit the ground.
4. Observe.
5. Feed your blob with burgers.
6. Get gud.
