may there will be fix for some issues bevore 9.x get to stable branch but i asume your guessing right. As the troop transport issue is anyway a minor issue (even if it is annoying) but this is a really older issue wich is hard to fix since there is no reproducable case with a 100% trigger.
If your able to reproduce the issue with success i suggest head over to the bugforum here https://empyriononline.com/forums/bugs.24/ and send a proper report, just to know there is a bug doesn't help much to fix it for the devs they need use cases to catch down the critters
