Why are all my champs glowing in aq?

Just joined in to aq, and all my champs are glowing, are they adjusting pl of champs today or something, or is it just a visual bug? Also a few there I've talked tos champs are glowing as well. Ps I haven't used any boosts, adjusted my masteries or anything like that.

Nope
You must have used a boost. You should know this by now
It's not from using a boost. It's a game glitch. Random boosts are being applied to champs when none have actually been used by the player.
4* R4 Thor
4* R4 Magik
4* R4 Crossbones
4* R4 Capt WW2
5* R2 Storm
3* R4 Angela
3* R4 Nebula
None of them have been boosted/leveled in any way. I keep a spreadsheet of all of my champs (rank, level, sig ability, PI), just to keep track of things.
What's even weirder is that none of their matching counterparts (i.e. 3* XB or 4* Storm) have been changed.
