When spreading an entire (64) stack of items across the inventory while the inventory place sound is set to 0.2 or higher, the game crashes.

Crash report:

Unable to reproduce, seems like another mod is trying to change the inventory while ExtraSounds is still reading from it.
As a workaround, I tried moving when the click sound is played - can you try adding this build of the mod to see whether it still happens?

Should be fixed by 1.1.
