Hello I was playing around with a new mod called remain in motion where I found out I can't craft the carriage engine, I do not know if it is intented but well here you know Kas_Boot
Tested in single player and it didnt work there either, there werent even a recipe in the NEI. Since this must be a bug in the actual mod there is nothing we can do from our side. I posted a issue in the github, so we can only hope the author will fix it.
thx for the time to find out, I'll wait playing with that mod until the next update comes out Kas_Boot
