This is the First Beta Version of the 1.21.1 Neoforge Port. It has many issues and is in no way shape or form as finished and clean working as the 1.20.1 Forge version of the mod. While it should not crash your game many things don't quite work yet. 

Also, the normal Dependency to MINT Lib is temporarily removed from the 1.21.1 Version as it has yet to be ported temporarily reducing mod compatibility! 

The fish bag should mostly work as far as we know also the base functionality of the Fishtank is working. The decor of the Fishtank sometimes gets placed wrong having parts of it sticking outside the actual fish tank. 

Also, the Hopper interactions for both the Fishtank and the Aquarists Table currently don't work! The recipes of the Items Crafted inside the Aquarists Table should work normally! 

Regardless of that if you find any issue not mentioned here Please go ahead and open a ticket on our Discord

The Neoforge Version will be Improved and Updated in the near Future!
