So, I went into the sewers, or more likely tried to, and in the entrance there were punches of these oozes, straightly charging at me. I heard from a DM that it might, or might not be, a bug for them to be there and attacking everyone, so I thought to post it up here for Arkov to tell how the things are, or should be.
digestive oozes
Digestive oozes appear (sometimes) when abandoned rat corpses decay. I never intended for them to overrun the sewers, though! They were just supposed to be flavorful.
I'm going to add a timer to those suckers and have -them- disappear after about fifteen seconds or so. That should fix it.
Fixed in v869.
