Yeah every time, they seem to get stuck at either end of the hallway.

Just booted up the game again and it's still occurring, so resetting/refreshing the page doesn't really help.
I'm on Arc browser which is basically Chrome if that helps.
It was on MacOS, just tried in Safari though and didn't seem to have the issue, so it's probably browser based.
Also the screenshot doesn't show this, but during gameplay the bots are moving left one frame and then right the next, which makes it look like they're facing both directions at the same time, so it could be related to the way that movement is handled.
Hope this helps!
