GregTech VS JMT-MCMT

There's an old GTCE bug that effects tin spawning but I don't know if this was ever fixed or not. Is your world's 0,0 in an ocean? If so, this sounds like it's still a problem. The solution is to apparently:

https://github.com/GregTechCE/GregTech/issues/1426 for the people that are on their phones

Does JEI say it should spawn with Mica? Quickly glancing over the default configs at https://github.com/GregTechCE/GregTech/tree/master/src/main/resources/assets/gregtech/worldgen/overworld, there doesn't seem to be any veins with Gypsum by default, so unless your admin have tweaked the configs to add it maybe you need to get it through other means (like H2SO4 + Limestone as proposed in another reply).

I found this on the GTCE github page: https://github.com/GregTechCE/GregTech/issues/44 That looks like the same error to me except for a different machine but it was apparently fixed in 2018.

They mentioned GregTech Intergalactical in the issue I was reading.

This pc is made only to run mc servers. So I ask you as a smooth brain mega pleb, is it possible to use more cores for a server? https://www.curseforge.com/minecraft/mc-mods/mcmt-multithreading/

https://www.curseforge.com/minecraft/mc-mods/mcmt-multithreading this could help

ah yeah that's what i meant. so yes it's only using 4 cores. you may be able to spread it over more cores. using for example - https://www.curseforge.com/minecraft/mc-mods/mcmt-multithreading

Then there is this mod https://www.curseforge.com/minecraft/mc-mods/mcmt-multithreading this looks like its geared more toward the sever side of things it can be used in single player as well. It won't increase frame rate however.

• Dimensional Threading

There are a few mods that have tried this before such as MCMT and C2ME (fabric), but they are quite unstable so I can't really recommend them. Minecraft isn't completely single threaded, the game runs an integrated server on a separate thread to the render among other things like networking, but it is still not very good.
