[Bug] Door/patient glitch renders the whole room (with patient) unusable

[EugeneFauci]

Why does this keep happening I'm replaying this level for about 3rd time. Room is un-removable and the patient cannot leave it (applies to surgeons sometimes). This is the 3rd level of ChrizmanTV and beyond campaign. (pictures at the bottom)

Steps to Reproduce

1. Load save game attached to this ticket

2. Build operating theatre

3. Wait till in-game error message appears - done

Is there a blocked path again @mugmuggy ?

[mugmuggy]

Looks like it.

[Alberth289346]

I think we need a more careful analysis of built rooms that all required paths exist

[lewri]

If it's a blocked off area, fixing it requires making sure this setting in the config.txt file is false
allow_blocking_off_areas (you'll have to restart the level)

(And if it is false, I think we have another problem too)
