• Confirm you are not using performance enhancers, such as optifine
• Confirm you have tested without external core mods/mixins

How did you end up on the Tinkers' Construct issue tracker? The error you pasted says its an IC2 API error caused by Railcraft.

Also, you failed to follow the issue template. You are supposed to test with fewer mods and you are supposed to test without performance enhancers.

What is Tinkers' Construct issue tracker ？

I question even more how you ended up here without knowing the answer to that question.

Because I saw this error reported in the server operation log, I don't know what the cause of this error is and whether it affects the use of the function. It seems that there is no impact for the time being, but after all, the server reported an error. I would like to ask you to help check the cause. If it is a problem with other mods, of course, go to the other mods to inquire about the problem.

This is not an issue with Tinkers Construct. I cannot help you with the issue because I did not write the mod that is generating the error. I asked how you ended up here because that error nowhere says "This is a Tinkers Construct error". The error says "IC2" and "Railcraft", two mods that are not Tinkers Construct. And no, it is not my job to talk to those other mods. You are free to talk to those other mods yourself. My job is to help with the mod I make.

We are not a modded error support forum, those exist if you want to talk to them. This issue tracker (where you are posting right now) can only help you with issues related to Tinkers Construct.
