Creative mode can break stores

Creative Mode does not use BlockDamageEvents.

The way around this is to right click instead of left clicking. I was having this issue until I realized that you watch for a left or right click on the chest. Once I started right clicking I was no longer destroying the chests.

Correct, this can be avoided, but the system is designed to not allow breaking stores, with special exceptions.
