Really appretiate if someone could take up this old mod and give it a compatability update. Currently kits wont claim because the items AntiItems puts in ur inventory will take up too much space even though they're hidden. Infact now that i think about it would it be better to update kits? This also create issue when saving kits as going to claim a kit will have the AntiItems stuff in it

Get  anti items to fix the problem maybe as its the newer plugin ?

There's a fix/bodge posted on that plugin, easy to do. You simply increase the number of slots by the amount of items you have in AntiItems.
