Players freezing upon joining

[TF2P Grim]

Hello, not sure if anyone else is having this issue. After the latest hotfix, suddenly anyone attempting to join my multiplayer game gets stuck at the initial spawn point (shrunken pod thing we presumably climbed out of). Music plays but they can't get to character select or see any movement.

Also tried waiting until everyone selects character before starting the game, and other players freeze immediately after hitting start.

Edit: I tried wiping out the ziplines but that didn't help. Also I can get people to connect in a new save file just fine. I'm wondering if I just blew my video memory budget building my village?

Hey, Grim! Do you know how many in-game days that save has?
