recently I've been seeing various conduits not rendering, with and without facades. i tried relogging, and restarting mc, but certain ones just didnt want to render.
ik of that feature, and that wasnt the issue. as random conduits were not rendering. rather all of one type (and i wasnt holding one)
I can confirm this is happening to me too. Usually it goes away after a few server restarts though. It's apparently a known ender IO issue, so don't think there's something MyM can do to fix it.
