Freeze on sliding through intra-map portals

First noticed this in the Krieg DLC, where it was just a little thing I had to keep in mind, but just froze mid-Guardian Takedown because I slid through the mid-map checkpoint portal.

I had gotten past the mid-boss for the first time, fought the fauna on the other side, and accidentally slipped off the cliff. Reset back at the portal, got turned around and somehow thought I was back in the mid-boss room. Traveled back, realized my misdirection, and slid through the portal to continue on in the map, whereupon the game froze as I contacted the portal. >_<
Not sure if I’m the only one getting this, as I’ve not heard it mentioned.
