I get an error when starting my server that says "Error while compiling QualityCrafting: 'PlayerInventory' does not contain a definition for 'FindItemUID' and no accessible extension method 'FindItemUID' accepting a first argument of type 'PlayerInventory' could be found (are you missing a using directive or an assembly reference?) | Line: 621, Pos: 41"

Any ideas why?

Unfortunately, the uMod version of Quality Crafting has not been updated in 2 years. The version on CodeFling (by the same author) seems to be working.

Ya, I found the mod on CodeFling and it works.
