Ever since getting the ''anti-magic coating formulae'' from the Item/alchemy shop, I keep getting an odd error message here and there (usually when, I think, the game tries to update the related quest).
Something about ''ID4 and ID25''... I skipped 1 or 2 Error messages before.
EDIT: and got a 3rd one about ''ERROR: Tried to close objective with ID5 of quest with ID25, but no such objective is registered.''
EDIT: aaaaaand ID6 with ID25.
