Hello,

I have the version railcraft-12.0.0 of railcraft used on Minecraft 1.12.2.
I encounter a difficulty with the installation of the tunnel boring machine, but, only on the seed -9363708386013540

When I put the machine on rails, it appears a fragment of seconds before dropping on the ground.

I tried to turn off all of my other mods, resourcepacks... but the problem remain.

Thanks for your help.

Fixed

I also experimented the same problem, for a moment I thought, as you did, that it was a fact of mod incompatibilities. Thanks for stopping me from becoming crazy 😂. I hope is solved soon.

You are not crazy. I experience the same error om the same seed - but also on a lot of other seeds.

But I have also experienced instances where it WORKS on that exact seed.

Singleplayer, creative.
