Did you ever finishing "seeing how it goes"? Because I only have the AL DC stuff, and I seem to be getting this dog piss bug, too. At first, it just happened when I tried to mop it up, but now it seems that just standing near a pee puddle makes pee rapidly spawn under the nearby victim. I don't know yet if this happens all the time or what. Guess I should look into it.
The binary search has revealed that nopedostalkers (fully updated) is once again at the cause of AL borkage, this time screwing up stuff during frozen time.
Tempus interuptus (time freezing spell) seems pretty badly MATY-made borked. Isolated a jump bug during frozen time where clicking on a sim jumps them and only allows entertain and primp. Time freezing itself works as it should. This is the DC, so no bvanimchildfix is involved. Spell works fine with no MATY stuff.
