Encountered a bug at the docks. I had a few gold, but could still buy as many ship upgrades as I want. I get negative gold, but can still change in to new ships. The reason I'm reporting this is that it's impossible to go back up to the cheaper ships from the more expensive. If I click down to the galley, I will have to stick with it - unless, of course, i cancel!

Don't know if it's a bug that the ships can be bought on credit, but the other thing must be a bug.
Feels like this is the most useless bug that will be reported. I doubt it will happen more than once a year that someone notices that "Hey! I can't change back to djonk! Guess I have to click cancel!".
Also, I've been wondering cause it makes no sense, is it a bug that it costs money to change from galleon (lvl 3) to galley(lvl 2)? Costs 10 gold. Same as from djonk to galley.
