Crash with MSVC++ runtime error upon moving

Repro: 100% after it started
Blocker: yep
Details: I'm in Wizard's Rest, player town, in online friends-only mode. Logged in to water my plants, then started running into town for supplies- I use dash a lot. I had played several hours last night no trouble. The last thing I saw before this issue, was one of my friends had logged out. Then it crashed. I can load back in, but as soon as I start moving forwards, crash.

Steps: All I have to do now is log back in, online play, friends-only mode, let things finish loading (town decor, etc.). I can look around a bit, but soon as I take a step forward, I'm back on the desktop.

User Specs: Intel i7, nvidia gtx 970, 32gb RAM, playing through Steam.

 

Updated details: If I load to world map, things are OK. I tried entering Owl's Head, and things were OK. I exited and went to Wizard's Rest, and before I tried moving, it crashed, possibly while it was loading decorations near the town center.

 

@Cryptomancer - sorry for the inconvenience, is this still happening?

 

As of R41 it has not happened. But since I was playing R40 a while before it started, it could still be there, I just haven't re-triggered it yet.
