Not sure whether to put this in bugs or suggestions, so I chose this forum (mostly because I'm not certain if it is a bug..)
I was creating another fleet and I wasn't looking at where my ships were. I had an LMM in Tortuga and 3 LMMs in Aiora. I clicked the one in Tortuga and upon realizing my mistake removed it. I assumed that when you choose a ship in a port, the fleet's location switches to that port, right? Then I should follow suit that if you remove that ship from the fleet, all ships not in a fleet could be placed into the empty fleet instead of having to delete it and make another one.
