i try to restart them every month or so and that seems to fix weird issues like that and connecting via bluetooth. worst case factory restarting and unplugging has also worked for me
i woke up one morning at like 5 am and one of my lights had just the green leds on in the middle of darkness. i'm sure my fish were solidly psyched that night
I recently had them all go haywire on me as well. Also mobius updated the AB+ schedule with a night mode which keeps the lights on all night as a moon light. If you check the colors it also has changed from the original AB+ setting. I had to factory reset all the lights then make a custom schedule with the OG AB+ setting and add that to all 6 of my radions.
