Furnace Upgrades 2.6.7

CanStackItem currently returns true for any upgraded furnace/oven causing them to turn into whatever you drag them ontop of. Changing line 1271 to return false fixes this issue.

This is still a problem and needs to be fixed, otherwise the item loses upgrades when being picked up. The line is different but the CanStackItem needs to return FALSE not TRUE, otherwise it will try to stack with any item.

Can you dm pls, Which stacks plugin you are using? does it fix for your stacks plugin only?

I wrote it out already. Your plugin returns TRUE to CanStackItem if it is an upgraded furnace, which means it is allowing it to stack with ANY item, causing bugs where when you pick it up it turns into the first stackable item in your inventory. You need to return FALSE so it cannot stack with any item. It has nothing to do with other plugins.
