When I place down a train the model is visible however when I get in the train, I can't use the train. I also get stuck inside the train. The only way to get out is by teleporting. When I try to remove the train, the model stays visible until I rejoin (this might be an issue with forge tho).

My server is 1.12.2.

need more info

I can't get info such as the logs at the moment. But the server is mohist 1.12.2 with 5gb of ram. I have immersive railroading as well as, immersive engineering, immersive veichles, UNU addon to immersive veichles, cubic chunks, and terra plus plus. If you need the logs i can give it but in a bit.

can't use plugin servers with IR must be Forge only

Oh. Well may I know what makes it not work with servers that run both mods and plugins?

Plugin API's highjack packets and change the order they are in this causes issues with IR packets and cause may issues like, unable to get in loco/rollingstock, not moving with rollingstock, unable to place down rollingstock and interacting with Rollingstock.

Thanks for the explanation and help
