Project Castaway 1.0.2
Mardonpol Inc.
- Fixed failing to authenticate when:
- Your Steam display name is not between 3 and 25 characters.
- Your Steam display name is not unique.
Fixed environment going black (or another erratic symptom) and inability to save when this happens.
Fixed inability to load certain old saves.
- Co-op window session code uses a monospaced font, for easier reading.
- Removed unnecessary player count on the co-op window.
These fixes should tackle the last two cases with authentication failing. If someone is still having authentication issues, please let us know on our community Discord!
Warm regards,
The project castaway team
