Problem when used by >1 Players

[xCraimax]

What happened?

The Item can be duped, when using the cauldron by 2 or more players. I assume (not tested), that it can be duped more than once - depends on the amount of players.

How can the bug be reproduced?

• Cook something in the Cauldron
• Then 2 players need to open the result menu
• The first player can take out the result
• The second player can take out the result aswell
• Now you duped the result

Expected Behaviour?

Not duping and synchronizing between players.

Yep, that is indeed a major oversight. I'll have a look at how I can securely handle multiple viewers.

I didn't find a way to synchronize the items between the GUIs reliably. So the fix for now will simply only allow one player at a time to view the cauldron GUI and block any other players from opening the GUI.
