Issue description

I was making my new mod when the recompilation failed with this error:

I only made an item (lavic wand) that when rightclicked on a block, it checks if there is air on it, if you have another item (mana), if true, it makes lava on that block and removes 1 mana from the inventory.

Can you help me?

Issue comments

You created an event with a condition if the slot contains, but instead of specifying the slot ID as a number, you left it at slotID. Remove this event and create it again with proper slot ID.

We will make it hard to make such mistakes with a future improved event editor. You can find first screenshots of it on Pylo's Twitter or Facebook page.
