As title states.
Sometimes some coffee plants require 3 ashes to start producing again. I'm still not sure what causes this. It doesn't seem to affect the other coffee plants even though they were all planted at the same time as the bugged plants. Seems to happen after season changes but cant be sure.
Also, sometimes, it will just stop accepting ash after taking 1 ash but still remain unfertilized.
Steps to Reproduce
Plant coffee. Fertilize once. If plant bugs out, may have to fertilize 2 more times. Randomly encountered.
