Distilling problem

[Leodriz]

Ok, i got problems distillg alchemical ingredients from parts i've found. As i understand from the description of the alchemical skill all that is needed is to use the mortar on the part in your inventory. When i try this with Sand (the only one in my party with the alchemy skill) nothing happens. It says "Sand uses item's special power" but that's it.

Am i missing something or is there something wrong with my game?

Ok, no need to answer, i found the problem. It seems one of the packs i put in the overide directory messed it up. I removed everything from there and now i works.
