- Mission Rewards adjusted to be rewarded for completing waves 10, 20, 30 and 40

[h2]Bug Fixes[/h2]
- Fixed some edge cases where Last Stand and Gauntlet skins were not properly being granted.
- Fixed an issue where mission rewards (Augmented Fate, Equipped Fate, Epic Beginnings, Fabricator Restock) were not granting properly.
- Fixed an issue where encounters would sometimes automatically complete when entering a room.
- Fixed a softlock in Last Stand if a player died during the prepare phase.

[h2]Known Issue[/h2]
- When completing Last Stand in Co-Op, players' camera may improperly adjust to the ground and other players may be invisible. Players can still exit the level through the teleporter and complete it.
