Lots of Freezes Today

I've been experiencing a lot of momentary freezes through this entire patch, usually not a problem - you just pause the game, it catches up, life goes on.

Today, I'm getting full game freezes every 30 minutes or so. But it doesn't crash. The network ping keeps going up and up as though I've DC'ed, but I haven't. I'm literally running a successful speedtest in the other window while watching the ping continue to climb.

What's different here is that when I kill the game and log back in, I'm experiencing a rollback. This has been on T15 maps every time, and when I log back in, the map is "Attemped", my Waystone is gone, the portals are all gone as though I failed it, and any experience I picked up is gone as well. I've lost 4 today as a result.

Not like a death. I'm not missing 10% exp. Just whatever I had gotten. T15 maps at level 92 don't get you more than maybe a bar, so I'm sure it's just rolling back whatever I'm getting in the map.
