When someone attempted to create a double chest using an ACC my plugin prevents that action. A bug that showed up caused a ACC entry to still be creating, effectively adding the ACC to the config file but the chest not physically being there. This would hypothetically allow you to create more ACCs by placing down a regular chest in the exact location of the ghost log. It was a simple mistake of not returning part of a code earlier then it should have been. That is now resolved and should also fix additional issues that showed up with 1.12 and lower.
