Hello there. I am using the latest version of both Quark and AutoReg Lib, as far as I know anyway.

The problem I am facing, which I can reproduce in any world and any gamemode, is that when there is a water filled bucket enchanted with infinity (through your mod) in the hotbar, and another regular, empty bucket next to it, switching from the infinity bucket to the regular bucket replaces the regular bucket with an exact duplicate of the infinity bucket. Even other properties like custom names are carried over. Basically I end up with 2 infinity water buckets.

This, as far as I have tested, only happens with WATER FILLED infinity buckets and REGULAR buckets. Does not happen if the regular bucket is also filled with some substance.

Hope you can fix it. Can send a video if you really need it.

PS: Quark is running among 50 other mods, however none of them add very major things, like quark, and do not add enchantments (except airhop) or affect enchanting in any way.
