[MC V1.10.2 | AM2 V1.5.0] Crash upon hitting or breaking an everstone

[SoraOkinawa]

Hey !

I play with these mods : Ars Magica 2, Inventory Tweaks, Iron Chest, Just Enough Items, Optifine, Xaero's Minimap, Wearable Backpacks.

When I play with Inventory Tweaks, I got a crash when I hit an everstone. Here's the error report : https://pastebin.com/rqSe0h1F

If I remove Inventory Tweaks, I got crashes when I break an everstone. So I can hit it normally, start breaking it, but when it should be destroyed and drop down, the game crashes. Here's the error report : https://pastebin.com/pyDfd0VU

If you need any other informations, just ask me.

EDIT : after another test, it appears that sometimes, even with InventoryTweaks removed, the game crashes when I hit the everstone.
