Minecraft Version: 1.11.2
**Inventory Tweaks Version: 1.62+beta.86 **

Decocraft Version: 2.4.1
EnderStorage Version: 2.3.0.112

Just noting here that there's an issue with each of these mods that seems to stem from a common problem: pulling (or placing) items into another mod's custom inventory with shift+click.

In the case of decocraft using shift+click to pull completed items out of the decobench causes the decobench to lock up entirely and stop working, as if an item is still in the output slot.

In the case of EnderStorage, attempting to mistakenly place an item in a full bag with shift+click, or attempting to pull an item out of a bag with shift+click when your inventory is full, causes a crash and boots you from the server.

The decocraft problem does not cause any notable error logs sadly, but if you need an error log for the EnderStorage crash, I can provide one.

If you aren't pressing any extra keys, inventory tweaks isn't doing anything with shift alone.

That's been a vanilla feature for quite a while now.

Wasn't aware of that. So that removes InvTweaks from the equation at the very least - however that still leaves shift+clicking as breaking the decobench.
