- Updated multiple maps to include fixes provided as feedback:
- Space Station 03; redesigned the gravity platforms for simplicity to reduce invisible collision.
- Redesigned lockboxes in WorldCorp maps which were swing doors, causing collision issues.
- Replaced swing doors with sliding doors in WorldCorp, DXE, and a few other maps. This alleviates issues of not being able to break open swing doors which were inheriting invincible surfaces from nearby walls.
- Fixed a BSP error which killed the player in Slums day 1.
- Fixed BSP error which made skyscrapers disappear in Corporate. (hopefully)

Updated WC sublevel blueprint map.

Fixed a freeze if using Biomod/Shifter.
