Sometimes when using lets say potions in combat while casting skills etc makes this particular potion kinda "blocked", they can't be activated with "q", nor directly from inventory, can't be split stuck etc, only relog seems like fixing it.
I reckon this is the same with the fish bug, where filleting causes it to bug out and you can't fillet and you have to relog. Seems to be items 'used' from inventory.
