as of now
saves are a little buggy
game crashes sometimes - sometimes coz she wants to crash, sometimes becouse you buy a new ship and you want it upgraded the same moment or to make it a flagship (workaround for me is to buy the ship save game and leave the port to do a battle than come to a port and try to upgrade/make it a flagship. 50/50 chance of fixing it this way)
money bug - sometimes i would come to a port, go to market first to sell my cargo to than go repair my ship or upgrade it when the game tells me i dont have enough money while 10 seconds ago i sold cargo worth 1500 gold
