  • Fixed supply costs for Armories, Observatories and Sentry Batteries

  • Fixed that pregame throwables stutter when thrown
  • May your target see your snowballs flying at their face smoothly now
  • Fixed that Alien Tunnels collapsed even if the second entrance was rebuilt, causing entrances to not connect to each other.
  • Fixed structure only damage did affect babbler shield real goodly. (Arcs can’t destroy babblers on you anymore)
  • Fixed that damage to the babbler shield didn’t stop new babblers from hatching
  • Fixed that a Gorge couldn’t re-attach their own Babblers
    • Keep those cuddly things warm again! Just don’t forget to give them out still, you greedy Babbler incubators..
  • Fixed babbler mine icon in the alien buy menu

    • The worst color. You know it. I know it.
  • Fixed that the voice chat bar overlapped with the spectator player info elements

  • Fixed client crash due to using an invalid shader reference
  • Fixed that GUIItems displaying text with non-zero alignments would sometimes be culled for being off-screen, even though they were still on-screen.
  • Fixed that if only a few babblers were removed on your babbler shield, they’d instantly repopulate instead of waiting the normal 2.5 seconds.
  • Fixed Tundra Exo minigun showing the Kodiak skin on one of its arms.
  • Fixed that enabling the Entity update routine delayed caused various script errors. Various script errors could occur by mixin logic that assumed that OnUpdate was called at least once before OnInitialized.
