A number of changes have been applied including:
1) moving the shuttle bay decompression chamber checkpoint further away from the door to fix spawning location issues.
2) reducing a large amount of unused files form the installation pack which has reduced the install size by nearly a gig!
Note - some players have reported an issue with the ACTIVATE and JUMP buttons being both mapped to E. This can be fixed by resetting mapping to defaults. If you are using a game controller, you also may find turning off Steam Controller input settings in Big Screen helpful.
Enjoy!
