Very hard to reproduce bug but it is currently messing my ravaging hunger colony up:
If a plant is harvest ready and a dups finishes the harvest job for that plant while the plant itself is in an animation due to having some not met requirement it will not drop a fruit which is obviously a bug because if the plant it harvest ready it doesn't matter if the plants growth conditions are met to get a fruit.
I observed this behavior two times now:
Once with Mealwood due to Natrual Gas and another time with Bristle Blossoms due to low pressure.
a) Have harvest ready plants b) Have some condition which cycles the growth condition of the plant (e.g. barelly enough pressure; chlorine/nat.gas/hydrogen ) c) Have a dup harvest the plant d) Timing & (Bad) Luck: Plant must cycle with animation at the moment the harvest job of the dup finsihes. e) If done correctly. There is no fruit.
