I decided to take a step back and take a more basic approach. What I did was to take the ItemCombos.txt out of the Main.pak archive and put it at the appropriate place for where a modded one might go. The result was that I no longer received the warning message about "corrupted/damaged blah-blah not being able to play online" (cut down, but I'm sure you know the one I mean), so obviously the game saw the file as being the original, official one, but as far as crafting was concerned - nothing I tried worked. Deduction: it's my game that failing somewhere. Question: Anybody out there had success (or similar failure) with any modding the Linux version of this game?
