Okay, there we go. Matter Overdrive had an issue with it's current build and multiplayer. I contacted the mod author and am awaiting a fix to the official build. But the issue is fixed.
Sorry guys, with this patch a huge issue occurred and I am working diligently to fix it. I am sorry for the delays.
Update 2.6.5! The Patch update that follows the Content update! Aren't we so predictable? Anyway, ProjectE's bags are fixed, new values are added, many game breaking bugs were fixed, and CompactMachines was removed. Have fun!
well done on youre milky mod packs Picture X3
