It showed when mod was first installed then checked inventory to equip belt and then the slot was no longer there

same thing the tool belt slot is never there for me at all

Hey same for me here ! I have saw a screenshot with a guy who got a belt slot just above the shield one ! do i absolutly need bauble to make it work ? @gigaherz

The custom slot screen is activated with the V key by default. In case of conflicts you can change/fix the key in the controls screen of minecraft

thx a lot for this information !

I'm not sure what you mean, does the "v" screen not appear? Or is the item gone from the slot?
