I just tried out the potion randomizing ability from the "Xenochemistry" ability in the Paranormal Investigator skillset. I cast the spell on a bottle of Acidum Salis and it turned into an Infernal Potion, or at least it seemed to; on further investigation the new Infernal Potion would not stack with my other Infernal Potions, and I was also unable to drink it. I've tried everything to try to get them to stack: dropping it and picking it back up, dropping the new potion on top of a stack of old ones on the ground, trying to manually combine them in my inventory, quitting and reloading the save; Nothing works. I have included the save file. The last two items in my inventory are a stack of real Infernal Potions and the new dummy Infernal Potion. EDIT: On further investigation, I was able to combine the stacks after exiting entirely out of the game and restarting the program. There's still a bug there somewhere though, because I shouldn't have had to do that. EDIT: I've since also had the non-stacking problem with a voltaic potion (although this one I was able to use without restarting the program)
It's likely a metadata problem. The funny thing is, that's what should be happening with quest items instead.
The potions go back to stacking when you reopen your save file; it's a shitty fix, but it works for now. EDIT: To clarify, this happens with all Xenochemistry potions, unfortunately, but they work fine if you quit to the title screen and then go back to your save.
