This is new.. Should I be worried?

[Neon Euc]

Just going through a few records on airdata that I haven't checked yet and seen this (screenshot below and circled in red)

So I checked the rest out and no motor issues, battery issues, etc... anyone know what this warning means?
Will try and upload the flight log later. But no idea what this means.. sounds like a motor issue but I know 100% I didn't get any ESC errors on screen while flying.

It is motor/esc related but can be caused by numerous issues. Possibly as simple as "prop drag" due to a large insect strike, a slightly chipped or unbalanced prop, etc.. You would most likely need to look at the aircraft .dat motor data to get more information however, since the device files do not contain that information.
