Hey there,
I have a Modded MC [1.21.1] Server running NeoForge [21.1.169] and it's been running fine. I added KubeJS [2101.7.1.build.181] and Rhino [2101.2.7.build.74] to the server and it starts to fail to boot. I loaded it fine without KubeJS and left Rhino on and it works, it's only when I put KubeJS on does it start to fail to boot.
I should point out that I'm running no scripts or anything through KubeJS on the server right now, I was simply preparing it for putting some scripts on. Also when I load it with KubeJS on there it fails to post a full latest.log. I'm going to post 2 latest.log files one with KubeJS and one without. Anymore information required please just ask, any help would be greatly appreciated.
