Dolgubon Set Crafter UI error DolgubonSetCrafterWindowLeftCraft_Clicked:3:

[gshillitani]

I've searched the forums, maybe not well enough? But I can't find anything regarding this error:

DolgubonSetCrafterWindowLeftCraft_Clicked:3: function expected instead of nil
stack traceback:
DolgubonSetCrafterWindowLeftCraft_Clicked:3: in function '(main chunk)'
|caaaaaa<Locals> self = ud, button = 1, ctrl = false, alt = false, shift = false, command = false </Locals>|r

Any ideas?
