Hi,
I just upgraded from 4.6.0p1 to 4.6.1p3 and started profiling my scene.
With 4.6.0 I had ~170 ContactReportTriggers in physics. After the upgrade I get ~6300 which I only had before moving all my triggers and colliders to different layers.
I didn’t change anything in the project after the upgrade.
Did anybody else notice this? It’s a clear bug in the new Unity version which makes it unusable for us.
