I just built another type of constructor that moves speed 13. It also is limited to speed 7. No, there has been no galactic meeting with a speed 7 constructor resolution.

There's a UP issue that can limit speed on constructors. Someone else had posted a simiiar problem, and it turned to be that.

i had the same problem and it was a UP resolution, BUT, the resolution was to set minimum speed to 5. With my techs i had speed of 7 i guess. my ships when built would start out as move 19/7 for the first move , they move the full amount , then they would go max of 7 parsecs. After the UP resolution was up, speeds returned to normal. SO if you look , you probly have a UP resolution setting minimum speed, that apparently sets max speed too. I know its not supose to so i guess its a bug

After the UP resolution was up, speeds returned to normal

The UP resolution on speed of consructors lasts the entire game. Very annoying.

Supposedly they have fixed this in 1.2. Install the update and that shouldn't happen any more.

I wanted to finish the game before updating again, but since I just finished.....

Is it possible there are starbases nearby? There is a starbase module that will slow down enemies. Perhaps this is what is happening?

Negative.... I did finally notice that the speed 21 constructors, when ready for launch, showed 21 of 7 movement points remaining and would move their full 21 when first launched and only 7 thereafter.

I'll update and load in the saved game to see if it still continues.

So you DID have the galactic resolution then? Why did you say that you didn't?

Until the latest beta, the UP resolution meant speed is (e.g.) 5, period. Not minimum, not base, just speed = 5, plus whatever global speed modifiers you might have. Extra engines not used . . .

Sounds like the resolution WAS the cause of the original problem. The beta fixes this problem with the resolution.
