Hot Fix March 27, 2015 Changelist

Stability Fixes

• Potential fix for font-related crash on the kit menu.
• Fixed common coop server crash when a bot was attacking a player that just disconnected.

Improvements

• Added Ukrainian localization.

Bug Fixes

• Fixed regression where capture progress was not stalling when there were equal numbers of attackers and defenders on a point.

• Station:
  • Fixed a few exploits around and at B push.
  • Fixed several small issues throughout the map.
• Tell:
  • Opened up the chokepoint near push objective A on Security side of canal.
  • Reworked layout of rooms adjacent to push objective B to mitigate route confusion from B to C.
  • Eliminated jumps up the hill to the left flank of push objective A by smoothing the terrain.
  • Fixed Security blockzone for push objective B. Insurgents can no longer fire into security spawn above A.
  • Removed crawlspace under ruins on left flank of push objective B approach.
  • Other minor fixes.
