you are the first one to be reporting it on the forums. We got a ticket about it but only one.. and need more information. We need the exact time it started, do you remember?
Slind, check this thread: Open - AE drives missing after crash chunkloading issue | MineYourMind Community Myself and Tyler reported it there since we felt it was a support issue.
Not a problem, I know you guys can be quite busy. Should be enough info in that thread for you to fix it
Added intersting info to my ticket. If cables are loaded but not connected to controller they dont seem to glitch same with drives
potential fix applied. please keep me posted. (you need to replace them once, but it should not happen again)
