loss of control of trade fleet after blockade

[Mugwump]

I had a 7 unit trade fleet on the Oki islands near Matsue and Tottori. It was blockaded for a tunr by the Wako and I got a message saying I'd lost access to spiffy warhorses. I took out the Wako fleet but the trade route didn't re-establish itself. When I clicked on my fleet, I found that I was unable to move them at all and I could only re-establish the trade route by sending an 8th trade ship into the trade circle.

Just save and reload when it happens

I did the same. I think it also happened after one of my ports was blockaded, but I didn't think to make a proper note of it, take a screenshot or save the game. Luckily I had plenty of trade ships knocking about.
