could you fix initial values for the loop to open this black line?
I see it on an every new map start.

I can decrease starting radius.
However, I would first like to know what changes do you do that causes it, which might help me make better fix?
Did you change any settings for initial-scan?
Did you modify any other settings for the game, such as starting area size etc that might be related?
Do you use any other mods?

I am using a lot of mods: SE, AAI and a lot of others (some of them are private)

The map settings:
period - 2
radius - 48

starting area size = 100

I have tried if changing the period is the cause and it is not.
I do not know why it happens.
Anyway, I have uploaded a new version with smaller starting radius.
Please, let me know if it fixes it for you.

fixed, thanks a lot!
