I had a very weird experience in the payload server... The other team had buffs from something or other at nearly all times, although it didn't appear to matter if they were close enough to a soldier or not. Also, some players who were near other players with the buff weren't showing a buff for them. Oh, and by buff I mean something like a soldier's buff banner.
Here's a video:
I can't tell if it's actually a buff or a graphical glitch, because several of the soldiers do in fact have buff banners and the like, so there's some of the genuine stuff mixed in, but it definitely seems out of place.
