Its as the title says really, I've built trade ports on my starbases and I noticed the the trade ship approaches the base - stops, then goes straight through it! This has also happened with a pirate attack as well, after an attack by the SB the pirate corsair broke off and also went through while the SB was still firing, the beams were firing at the inside of the SB.
This is most noticeable on the argonev, but its present on the others as well. The part I don't get is that orbital refinery and trade ports don't have this problem with larger ships, would the cost of adding 'solid starbase' avoidance cause a heavy slowdown?
