I dunno, that sounds pretty bad to me. Even with the door closed, the fucking spores can still permeate the whole space pretty easily. If it's that thick, I'd be surprised if you weren't still being exposed quite a bit unfortunately. And from my limited understanding, a person may not feel effected by it at all until a certain threshold is reached. A threshold of either amount of exposure, length of time exposed, or getting sick in some other way just being too much for the immune system which then suddenly can't deal with the mold toxins even though it previously had.

Yes, the Maoist revolution can't come soon enough.

Also, too bad BMF isn't still around to guide us through these issues.
