When a path to a flag is closed, everyone inside it must be dead. Otherwise they will stuck there and may be forced to use killbind

Also it may lead to a softlock when someone will stay inside with a flag, since control point does not reset, when a flag is taken: https://imgur.com/a/V2T3blk

this is news to me. That door automatically closes when its control point resets, but a trigger inside the room tells it not to if any players are touching it. If all players inside exit the trigger, it closes the door. There should be no way for it to lock anyone inside, nor should there be any way for it to lock before the relevant control point resets, as it has in your screenshots.

Testing on my own and I am unable to recreate this. Even constantly noclipping in and out quickly provides no success. If you can provide more information I'd highly value it!

Ah nevermind, found the cause! Just couldn't find it because i was testing on my own. having someone inside the room while its open, letting the point reset, and then capping again has the door close when its supposed to open. Thank you for noticing this!
