The new version of the mod requires updating tinkers construct. Is it possible to make it so that it would not need to be updated?

version 39 also causes an error.
I am not a server administrator, I am building an assembly, I am engaged in crafting, so I do not know exactly what bugs there are

Consider compatibility in R39.

Actually, I'm curious about your fixes on this Tinkers' Construct 2 version,maybe I can help you with that so you can update it.

To be honest, I don't think anyone would use an outdated mod that hasn't been updated in almost 3 years...

We do not update the mod on the server, so as not to lose numerous fixes, duplicates. Anyway, thanks.

Supported on R40.

Unfortunately, my problem has not been solved, I will be very glad if you correct it in the future
