Hello!
While playing on the server, the client crashes (your mods are not installed on the server).

Yes, yes, sorry, I remembered.
A mod that is incompatible with yours is RTM (trains).
I wrote to the developer of this mod, but he does not answer and, if I am not mistaken, my messages are sent to spam. So I can not convey to him the problem of incompatibility between your and his mods. Unfortunately.
Once again I apologize for my forgetfulness!

You have like 200 mods installed or so. It's a mod incompatibility. You posted the same issue a few months ago.

Basically, you have to remove a mod that causes this issue. We don't know which mod it is, so it's up to you to figure it out.

That sucks, but there is nothing can be done to fix this issue on my mods' side. Thanks for letting us know which mod it was! 👍
