Unable to deserialize packet pid = 1

Got this while in town in act 3 today, the game froze then went black, this is the first time I have ever had an error.

There was a patch today before this error showed up, Patch 0.11.5e

Unable to deserialize packet pid = 1

had to reboot PC to close game.

I have the same problem since the latest patch. The client just crashes after selecting a character.

I had this today; ALT-TABbed to see the error. PoE screen is static and unresponsive, but continues to play the music.

I have been getting these exception errors with unable to deserialize package pid = <insert number>

Happens when changing zones, and mostly when entering a town (not hideout).
