Graphical Bug - HUD healthbar not visible

Hiyo So i had this bug, as per the picture; the green in the healthbar at the bottom of the HUD would disappear, leaving just a line showing where the %health should be. It reset a couple of times during the match when I died, then very quickly repeated.

I also had some pretty strange lag during that game and the game before, so maybe ritos servers are just having a bit of a giggle right now.
