Buffer underflow?

I just opened a tier-1 scourge-tier-10 map in my hideout and the game crashed. Steam updated Path of Exile for a few seconds when I tried launching it again, and now I'm getting "Buffer underflow" errors right before my character loads into town. I didn't change anything, except that patch automatically applied. It seems persistent. Would love to get that map back or at least my portals. :(

I just got this too. I'm on windows 7 still.

I got a "Deserialized a mod that we don't recognise" as the exception

Tried restarting Steam, and that seemed to fix it.

We're back boyz, just lost a map :)
Same with me. I had Zana in one of my maps. Chose Death and Taxes unique map and it immediately gave me an error. Now I keep getting Buffer Underflow. I verified all my files which at least let me log back on my character, but going back in the map I got Buffer Underflow again.
+1 here. Doing a grand heist, 1st wing fine, went back to town to save items, upon re-entering heist portal it throws 'buffer underflow' and closes game. We had 4 people running the heist, 2 of them had the error thrown, 2 of them could proceed with the heist as usual. Log from one of the PCs that had the error:
