Roon doesn't see my external hard drive

After update, 3.1 build 269, Roon no longer sees my external hard drive, it doesn’t appear in storage settings even though its on my desktop, Audirvana + and iTunes can both see it and access files stored on it. I also think the update maybe responsible for some strange behaviour my iMac started exhibiting around the same time such as highlighting of items/options in menu drop down boxes flickering between options when trying to select one, system sound effects randomly sounding and continuing until I switch it off inSystem Preferences and others, these behaviours are all random.
