So I have found these bugs from original sc: not expansion of remastered.
1- when i finished terrain campaing and start zerg, i cant choose anymore specific terrain maps to replay it; instead the terrain campaing just starts from the bottom, also protos campaing show falsely that terrain campaing incomplete it should say zerg campaing incomplete (have finish zerg campaing yet)
2- when restarting game game speed settings are reseted back to maxium speed (in single player game) each time
3- game timer resets if you play campaing map more than 1 hours it start back from 00:00 (minute); forexample if your game time is 1 hour 3 minutes 30 seconds it show only 3 minutes 30 seconds
