To reproduce: Play LE on two different PC’s
- On first PC (Notebook) play the timeline until you have the Boss milestone to confront the Boss.
- Close Game and let Steam Synchronice.
- Went to other PC (Tower) and start the game.
- Go to your Last Monolith and you see you must do a Map again to get the Boss milestone enabled.
This happens all the time that you loose timeline Progress when you switch PC’s
