Hi all, short description what happend: 1. steam auto-upgrades to 0.25 from 0.24.2 2. find billions of science points in my science mode savegame (w/o cheating intention!!) 3. orbiting in savegame is nearly impossible... seems like physics time is totally out of sync with graphics time which is again out of sync with maneuver planning time 4. all saved flights are lost (several unmanned probes in stable orbits just vanished) 5. Starting a New Game works perfectly (but I don't want to loose my science progress). comparing 0.25ed savegame with old backup i find missing decimal points all over the place. Here one example: backup from 0.24.2: " SCENARIO { name = ProgressTracking scene = 7, 8, 5 Progress { FirstLaunch { completed = 103.759999999997 } "after loading in 0.25 " SCENARIO { name = ProgressTracking scene = 7, 8, 5 Progress { FirstLaunch { completed = 103759999999997 }" The wrong numbers might clearly mess things up.
