Hotfix 0.19.2.7

Hey everyone! Here's a small hotfix following the update today.

We fixed the following urgent bugs:

• Co-op Challenge Invites no longer have strangers dumped in them!
  
• Beating chapter 5 on insane is an upcoming achievement that we surfaced too soon. Removed it from the list for now!
  
• Some players experienced a crash on startup related to their language. The game now has more safeguards against data corruption in this area and falls back on English!
  

Let us know if you find any more bugs!
Cheers,
Erik
