Action RPG Inventory System

Hrmm that’s odd :C
In the UI container widget on the eventgraph can you check if the “Server: Close Container” section is hooked up? it sounds like it might not be firing the ServerCloseContainer() in the OnClicked(CloseButton) Event.
Double check there and see if the controller reference and inventory manager component are hooked up and if they are try adding a breakpoint and see if the button is calling the function.
