I abandonned my ship due to early game pirates, and sort of successfully fled, but after this I don't encouter any other ship on galaxy map, I played few hours without any encounter even in hostiles territories. If i keep the galaxy and create a new captain, i have almost immediatly a contact and reloading old captain don't solve the issue.

Thanks, did you ever get a new ship? or are you still in the escape pod? You can't get attacked if you are still flying around in the escape pod.

I got a new ship right after this battle. I don't have any new contact with this new ship or fleet.
