Full information on The Glast Gambit: Update 19.5 can be found here:

Scripts:

• We're running a script to fix accounts who received no change to their alignment after The Glast Gambit -this script has run, but unfortunately the Alignment values are still bugged. Another (hopefully) final fix will be coming, either today or in the new year.
• We also have a repair script for the missing drawings from The Glast Gambit

EDIT: Both of these scripts are complete. All affected accounts should be updated.

Changes:

• Increase Antiserum drop rate for 4 player squads in Infested Salvage
• Reduced Armor drain & damage at 0 Armor in Infested Salvage

Fixes:

• Fixed some spawning issues in Infested Salvage
• Fixed Armor not resetting after respawn in Infested Salvage
• Fixed points scored in the last round not counting towards your Wager score in the Index
• Fixed some of the Index Noggles (note: if you placed Derim Zahn, M-WAM, or Tia Mayn before the hotfix you just need to place it again to fix the mesh used).
