I've just updated to 4.1.6. After Node Red restarted, my subflows have all changed to the same colour in the Palette (different colour on each instance).
Each of my Node Red instances has the same issue once upgraded. When I drag and drop the subflow node , it reverts back to the colour I defined for it , just not in the Palette.
I've tried editing the subflow template , edit properties, then colour , deploy , which seems to work, then reverts after editing a few subflow templates (seems random how many and which ones).
Obviously, I can restore, but wondered if someone has come across this or if this is something new in 4.1.6?
