[Fighters returning to circle mothership cause serious hickups]

This issue is still happening.
The probable cause is the fighter collision detection when large group of fighters return in a tight bunch.

[Fighters returning to circle mothership cause serious hickups]

This issue is more noticeable the more there are fighters.

For example, with 4 shiploads of squads, the hickups can last several seconds.

What makes these hickups even more weird is they completely disappear when ordering the squads to return.

I have two /profile commands stats files.
One, while the lags occurred, and second when they disappeared after giving the return order.
I'm not sure how to paste them since they are over 60 megs each.

I heard that asteroids reappear after some time, is that true?

 

Sneaky, did you manage to set up those loops in a way that benefits from asteroids reappearing? Or do you just find new places to mine manually, after those asteroid fields you mentioned are mined of all resources?

 

Asteroids do replenish after a while.

I do not know how long it exactly takes, but I've found that having one miner looping between two  +2k asteroid belts keeps it running forever.

 

Also using one Resource Depot per miner is safer, since sometimes they try to refine at the same time and one of them bugs out and you  need to reorder the loop for it.

Having a few mining ships profits very easy money.

 

I currently have 5 mining ships looping between two big asteroid fields in Xenion region which profits me around 200 million credits per hour.

I haven't made marketing or producing goods so I can't comment on those. Bought this game shortly after Steam release.
