Updating from ModernFix 5.2.5 to Moderfix 5.3.1 for Fabric 1.20.1 causes some blocks to not render properly (example chests).
This only happens in the new version afaik and reverting back fixes it. Also this was tested with additional optimization mods such as the latest version of Enhaced Block Entities

5.2.5

5.3.1

Think this is a duplicate of #169, update Fabric API for now.
