[Bug] Ships stuck on other ships.

Basically I often get medium frigates stuck behind long range cruisers. They can’t move over the cruisers, so they end doing nothing until the cruisers are dead (and thus not blocking the way). Seems to be a result of the “anti-stack” code.

I’m getting this a lot, pile ups of ships that aren’t able to figure out how to unjam themselves and with escorts completely stuck a couple of miles back.
