Full Slabs crashes with "True Secret Rooms" ; Lagging in Creative Mod

[Adonyashka]

When i tried to place Camo slab from True Secret Rooms mod, it just crashed... Version 3.12
Also, when i started a new world, it caused really-really bad lags (120 FPS --> 4 fps) in Creative Inventory... Version 3.13
And more, in mod Version 3.12 all mods' slabs' textures missing
Here's crash log for first issue

Do you use Dashloader at all? I'm not sure that's the issue, but it is something I might have to think about

This might be an issue on True Secret Rooms' end. I tested True Secret Rooms alone and camo slabs and stairs from that mod don't work correctly, instead of being slabs and stairs, they turn into full blocks. This might cause FullSlabs to interpret them incorrectly and cause the crash, which is then technically blamed on FullSlabs.

I created an issue on their github here, if they release a new version, I will test it again and see if the issue persists.

And I can't reproduce the lagging issue at all, even with my 366 mods modpack.
