First, I play Single-player with mods, so hopefully someone on officials can check this out to save me the trouble of disabling mods for testing.
I tried running the Dregs dungeon to check out the changes. First crash happened less than a minute after entering. Reloaded game, cleared the first room (Komodo boss was a nice surprise), got past the first 3 skeletons and it crashed again.
I’ll keep trying and update with the total number of crashes it takes to beat the dungeon. Have to say 2 crashes in the first few minutes does not bode well.
Total crash count = 6
First crash was seemingly random in the first room.
Second and third were at the first Large Chest (right side of the room after the first three skeletons)
Fourth, fifth and sixth crashes were at the other Large chests throughout the dungeon.
I was able to access the Large Chests in the boss room as well as the Legendary Chests (I really like the new look of those). So not a complete loss, but it was very disappointing not to be able to collect the best of the new loot chests.
