Havoc Assignment launch as host broken after errors 3001 and 3013

Issue Type (Required):

Matchmaking

Issue Description (Required):

Got an error 3001 on two last tries for Havoc 27. It removed last two skulls and left me with 0, but I didn’t get demoted and didn`t get new mission of lower rank.
After that I can’t start my Havoc lobby. Pressing “Play” button doesn’t do anything, and my teammates don’t get “Accept/Decline” window. Reloading game, restarting PC, removing mods doesn’t fix the problem.

It looks like exactly the same issue allethargic had on December 4th.
(Bugged "Play" button in Havoc)

Joining others` mission is no problem though.
