Random bug: Chemists keep drugs in inventory during transformation

[DannSKiller]

Hi,
I'm experiencing a strange and annoying issue with the chemists in the game. Randomly, some chemists keep the drugs (like cocaine) in their inventory during the transformation process for no clear reason.

The bug usually happens around the 4th or 5th step out of the 8 in the transformation chain. Instead of proceeding normally, the chemist just "holds on" to the drug, which blocks the entire production line.

Has anyone else encountered this issue? Is there any fix or workaround to prevent it?
Thanks in advance for your help!

Yes, has happened to me too. I just kill the chemist, do his duties, then sleep. if it happens again next day, then he gets fired and i replace him.
