I've finished researching all engines. After i did the last research catagory it seems my constructors wont go the full distance they shoudl. This is not crashing the game, but it is affecting the distance my constructors travel each turn. I've tried build an entire new constructor ship (several times) from scratch with the same results. When a ship finishes building it shows that it has 23/8 moves left. It will move 23 spaces and stop. On it's next turn it only reads as 8/8 and will only go 8 spaces. If you need more info let me know, I'll see if i can dig out anything you request.
