I have a printer farm with 16 Ultimaker 2+ where I use Octoprint to connect my iMac to the printers. I just updated Cura from 4.4.1 to 4.5.0. But when I started Cura, all my printers were gone from the preset printers list, except the one I used last. I added all printers again, but when I closed Cura and started it again, all printers except the one I used last were gone again! Does anybody know what the problem is and how to fix it? PS: When I add one of the printers, both O01U2+ and O01U2+ #2 is added to the list.
