This is what a Developer said.
Hello Armageddon,
some of the game balancing was changed to make the game harder. We did this because some players were complaining about lack of challenge.
The repair droid functionality was changed to prevent exploits. This change was necessary and cannot be reversed. Please keep an eye on the forum thread where this is being discussed.
We will observe to see how the new balancing works out and make changes if appropriate.
Thank you.
