playing a modpack called skyopolis 4. when i switch to the schematic item in my hotbar and it has a schematic loaded unto it it crashes the game and i have to delete the schematic in the folder in order to open the world. have a feeling it is a problem with create and immersive engineering being used at the same time cause i have done schematics that dont have immersive engineering blocks in it no problem.

I also am having this issue with one of my modpacks on our server. This issue does not crash the server, just the client.

The only temporary fix I have found is to delete the entry in the playerdata file and if in singleplayer edit the level.dat, and delete the schematic.

"fancy menu" mod incompatability

So the issue is "fancy menu" and not Create?

well, it's both Create and fancy menu being not compatible... report that to modpack author too btw

Thanks.
