Modpack version
1.77

Issue
There are a lot of items that don't have a recipe and cycled in the Gates ultimate mission because I can't make a cutting machine

I'm not sure what the issue is to be honest, could you please rephrase?

I can't make the machine I need，but the quest needs these things

such as cutting machine、rftoolscontrol:cpu_core_500、computercraft:turtle_expanded

Did you modify the modpack in any way? Do you see errors in the chat when you log in?

I added "i18nupdatemod-1.12.2-1.0.8"、"OptiFine_1.12.2_HD_U_F5""JustEnoughCharacters-1.12.0-3.4.3", on the client.I am Chinese, so I added these mods.But these are just auxiliary mods

Please re-install the modpack and see if the issues persist.

I am trying and will give you a reply later，thanks

Sorry for the trouble. The problem has been solved.Thank you for your answer

Is OptiFine problem, you can add a list of incompatibilities to tell the following players

Optifine does not cause recipe issues afaik.

I don't support Optifine because it can (and often does) produce tons and tons of issues with mods. Keeping a list of incompatibilities would take a very large amount of maintenance, for a mod I'm already trying to avoid supporting.

If people want to use Optifine that's just fine, but they're on their own, just like if they add other mods to the pack.

Thanks for reminding, but the problem of the recipe this time is really Optifine's problem
