Overwriting the internal table.concat seems to be creating problems with other mods.

Failed to load mods: cf-lib/util/table.lua:82: bad argument #1 of 2 to 'pairs' (table expected, got string)

Ok, I'll look for a better solution.

I got this too -- but only in the very specific case of having Lignumis and !skins active at the same time. I took a look at the scripts, but my lua skills are not advanced enough to determine why this is.

Should be fixed.

Awesome! Seems to work perfectly now.
