Whenever using the schematic item with any of these blocks:
Crafting Station
Tinker Station
Part Builder
Tinker's Anvil
the game will immediately crash when previewing the schematic.

Crash reports for each block:

Tinker Station: https://pastebin.com/qZ28FSGk
Part Builder: https://pastebin.com/c4ciFJKd
Tinker's Anvil: https://pastebin.com/ukQeFfTw

For reference, here's a link to an issue I made on Tinker's Construct GitHub:
SlimeKnights/TinkersConstruct/issues/4521

Versions:
Minecraft: 1.16.5
Forge: 36.1.0 and 36.1.25, both crash
Mantle (required dependency) 1.6.103
Tinker's Construct: 3.0.4.171
Create: 0.3.1c

Mods in question:
Tinker's Construct ( https://www.curseforge.com/minecraft/mc-mods/tinkers-construct/files/3326523 )
Mantle, a required dependency: ( https://www.curseforge.com/minecraft/mc-mods/mantle/files/3326538 )

Thank you for taking the time to make a report. This issue has already been fixed on our dev branch so it should be working correctly in the next release of Create.

Thanks for the speedy response! My apologies, I didn't find that issue when searching earlier.
