It seems there is a hardcoded limit on how far ships, or atleast, how far my freighter mark 3 with 14 sectors supply range can travel. It seems that it is limited to half of that or so. I know this because i upgraded it to a later model just to make sure and the range which it can travel didnt change one bit (and yes, i did it properly with the life support and not the engines upgrading)
So is there a hardcoded limit on how far freighters can travel. And if so, could you remove it as it is very very... strange. That there should be a limit on how long they can travel yet still be able to place life support modules on them to go beyond that range. In my gigantic galaxy with rare stars and star clusters, the trade routes end up being exceptionally long so if i cant establish routes longer than 1/3rd of the length of the galaxy it severly limits my income.
Might be expandable by building starbases but that would be a bad idea as i would then have to protect a starbase 10 sectors away from my home.
