I have 2 DOS and 2 DDRs connected in my system and even though i had setup and could see normally both DDRs in Fusion, for a while now they're either 'appearing & disappearing' under new tiles and the strangest thing is even after i find them again and put them in my dashboard they're disappearing again....I have tried pretty much everything, restarting the whole Apex, re-installing both DDRs, resetting...everything, but still this problem persists....

In a different aquarium (with a different Apex) i have another DOS and DDR attached without any problems since i installed them years ago...

Any ideas?
