Halo Reach radar broken?

Anybody notice Halo Reach’s radar is buggy as of late? Dots on map are still solid even when enemies are above or below you.

Nope. I haven’t noticed anything out of the ordinary. Certain areas in maps, such as the bathroom on Powerhouse, the dot will stay solid if you are in there and someone is above you upstairs (or vice versa). You might just be encountering it in these places?

Haven’t noticed anything on the radar but I have noticed people being launched like a catapult for no reason.

I played a bunch of games tonight and noticed nothing out of the ordinary. As Freak_A_Fan said, there are certain parts of maps where enemies can be above or below you yet show up as bright red circles, the prime example being as he states in the Green Residence on Powerhouse.
