I'm having the issue of the trainbuilder refusing to be placed on the rail. I tried with vertical and horizontal rails, I tried with ghost rails, I tried with legacy rails. Nothing works. I can place down the depots, but train controllers and builders I can't place at all. It just keeps saying "straight rail is in the way"

I tested the latest version of the mod and couldn't reproduce the issue.

Factorio version: 2.1.12
Mod version: 0.5.7

Everything works correctly on my end. I didn't encounter any errors or unexpected behavior while using this version of the mod with Factorio 2.1.12.

Could you please tell me your exact Factorio version and mod version?

Mod version 0.4.10
Factorio version 2.0.77
I updated everything I could to the latest public version I had, I had no other options for it, and I updated my mods before starting the todays session

I currently only have Factorio 2.1 installed and no longer have a 2.0 installation. I'll try to investigate the issue on Factorio 2.0 today, and if I find the cause, I'll work on a fix.
