IInventory.isItemValidForSlot not being called

[CountNoobula]

Hey guys!

 

Firstly, thanks for all the support in the past, I humbly come once again to ask for advice.

 

I am busy working on a little exchange table system, I am trying to limit the objects that can go into the slots though. To do this, I am using the isItemValidForSlot method, it doesn't seem to be called though.

Could you guys provide some help/insight please?
