I'm sure you have your reasons for making these changes and I am enjoying the game so don't have anything negative to say as I am quite new.

The only issue I have now is that I can't do any missions at all as I only just managed to get my ship skill to the level where I can make explorers and now I will have to wait days to get enough resources to get my Mission Control to level 1 :-(

Maybe you could set everyone's Mission Control to level 1 if they are at 0? No new user will ever be level 0 so it seems unfair that existing users now have to upgrade especially when it is going to take days (or maybe even over a week) to produce enough resources.

Thanks!
