Mac Zombie Fortress Solo mode woes

Hi,

Category: KAG Client
Operating system: Mac v10.6.8
Build number: 591
Description: When I click on Zombie Fortress in the Solo menu, a light blue background appears with nothing else present. No character, no land, no inventory, etc. So I hit escape to get out of it and click on the Sandbox mode. Now a world generates. When I go back to Zombie Fortress, the same world I had in Sandbox mode appears in the Zombie Fortress mode, just how I left it. However, no zombies or NPCs spawn and it never turns to night. It's pretty much exactly the same as Sandbox mode.
Steps to reproduce: Click on Solo > Zombie Fortress; see blue screen; exit Zombie Fortress; click on Solo > Sandbox; exit Sandbox; click on Zombie Fortress; wonder why it looks the same as Sandbox and has no zombies
Screenshots/Videos: I can add screenshots or video if requested but hopefully that description was clear enough!

Thanks!

Oops sorry. Edited!

Re: Classic KAG -- I don't think so, but how would I check to find out?

 

Build 591 is Classic.
Which no longer receives updates.

 

Whaaaat. I've been playing Classic all this time thinking it was the regular game. Wow, I guess I'll check out the new version. Still wonder why the Zombie Fortress mode returns a blank screen on Classic, though? Maybe it was incomplete at the time of the transition to the "Deluxe" (or whatever it's called) version of KAG?
