As discussed, there are two specific door entities which lost all collision when bone_followers were disabled in early versions to fix serious lag issues on some maps.
Since this noticeably breaks maps using these doors, a hard coded exception to reenable collision on these two entities would be nice. Assuming this doesn't bring the old problems back.
I'm not certain of the exact entity names, but both door entities can be found in zm_alcazar:
The doors on the elevators
The large metal door in front of the zombie spawn at the bottom of the elevator
