Fixed you beautiful legand

This bug is caused from a library called "nbtcrafting", the current solution is to put nbtcrafting 2.0.19 with this mod, because the latest release has this bug. When i build 5.0.0 i forgot to set that version intead of latest. Sorry for the inconvenience.
Please respond if this fixes the issue.

Can i download the same file or do I need to build the mod myself?

as there is only the same release from 3 days ago which version number hasn't changed

and i dont know how to compile the jar

You don't need to compile anything, just download nbtcrafting 2.0.19 from here. And add it to your modpack.
This will replace the nbtcrafting that this mod includes, and fix the disconnects.
