I'm using your Torch Slab Mod in my 1.15.2 mod pack. When I updated from v1.6.8 to v1.6.10 my client crashes.

• OS: Linux Mint 19.3
• Minecraft: 1.15.2
• Torch Slab Mod mc 1.15.2 v1.6.10

Also: When I revert to v1.6.8 and updated FancyMenuWhen my client crashes and it looks like Torch Slab Mod is the culprit:

@ClaudiusMinimus Fancymenu is working on updating to the most released version of forge, I contacted the developer this morning

Does the 1.6.13 patch fix your crash issue?

Sorry, it does not, though if I just load your mod and the latest of fancymenu it loads fine. There must be another conflict.
