I'm one of the Blaze Map devs, and have found an issue with our rendering that only occurs when EnhancedVisuals is also present, and only in survival mode (not creative).

To avoid repeating myself, will just link directly to the thread I made in your Discord server outlining the information I found relating to this issue, including a potential cause in your code. Would love to work together to get this fixed so modpackers can enjoy using both of our work!

This was tested within the last week using the latest available version of both mods in Minecraft 1.20.1.

Fixed in the newest version. Again thanks for reporting this issue!
