Hey guys, been trying to get ahold of Nos or King to bring this up, but I found a setting in sign shop that may allow durability items to be sold.

I'm thinking from the looks of this, if you were to change the buy variable in the config to takeVariablePlayerItems{acceptdamaged}, that it may help with the selling of items with charge. Dunno if you guys saw this already and have tried.
Thanks!
