Noticed I could not put an upgrade on a trader ship nor could I put it into upgrade storage. When I did so and sailed away, it put all back into the port warehouse. I don't know if issue has been fixed, but it is real concerting that purchases cannot be stored or transported based on a gliche. I reported the problem right away during the game using the F11 key. Additionally, couldn't transport cannon in a trader ship to another port warehouse. Loaded cannon on trader ship and upon sailing found they were all back in the warehouse.
