I've had my colony open for two days straight and during that time i gained independance and growed my colony alot but my vehicles started bugging, moving without reason, glitching itno buildings etc. I decided to restart browser and when i opened it again i have game state from like 4 days ago. Is it possible to restore my save?
PS: I was logged in using facebook
Log out of Facebook and see if your game goes back to where it should be. If not, check your device for .mcz or .mcb files and try and load one of those if found via "More Options" -> "Game Data". If you don't find any of these then you may have lost your saves. Always, always make a manual backup of your colony. You can also try logging out of Facebook and logging in again to see if it will restore your progress, but do not depend on Facebook to keep a backup of your game. Make a backup yourself.
