First camapgin is running for 30 years now. Some obersavtions.
1. Ghost ships Scrapped ships reappear in battle fleets
2. Missing ships I ordered all my ships to stay in port, yet I am missing five out of 45
3. Resaerch time Research still takes way too long. After 30 years I still only have coal fired engines, even though I have had a full tech budget since day one and have focused on engine technology.
4. Ships in enemy ports Austro-Hungary has 100 ships, but in their ports are at least twice that number
4. General bugs with the enemies Three enemy fleets have more than 350-450 active ships each, massive funds of gazillion dollars, maximum of average tech level
