I have been working on a door that you need a certain key for it. So I renamed a stack of a trap hooks. It works perfectly, but directly after a server restart, and something not even then, it won't stack anymore. This is if the renamed item is kept in 2 different stacks (41 and 23) at the server restart. Even if it is kept as a single item, it no longer works. This makes door requiring a key impossible to achieve in this server.
