Slime offgasing even when the pressure is over 1800g

auto_save.zip

I tried again, so at the beginning of cycle 97, everything is fine. But at near the end of cycle 97, the auto sweeper in the mushroom farm stopped working, it fetched 120g slime but always failed to deliver and that slime started to offgasing. At that same moment, 4 pacus in that pool die and 4 new tiny pacus hatched from eggs. It might be the pacus that cause this bug, which is weird. Please take a look at my save game. Thanks.
