It looks like you’re running a Minecraft 1.12.2 server, if you are trying to use NTM x4214 in it then that’s your problem since it is ONLY for Minecraft 1.7.10, there is a 1.12.2 fork available but features and functions may be different in it since it’s a separate project. You can find it here: https://github.com/Drillgon200/Hbm-s-Nuclear-Tech-GIT/releases

edit: Beaten to the punch by 39 seconds

i placed a radar but the server crashed much later so i don't know if that's the reason

i'm already using the 1.12.2 fork, and the server worked until it crashed and now i get this error when starting it

Got it, I had some morning brain and just thought you posted in the wrong area

by the sound of it the crash is coming from a Radar tile entity, did you or someone else happen to place a radar before the server crashed? I don’t know what the solution to the issue would be for now but at least we can try to drill down to the cause
