Two days after activating DLC11 I experienced a massive lag. So, I restarted with an older savegame and activated DLC 11 again to see if it was the DLC in general that might causes the lag, but it wasn’t. The game did run smoothly as before. Then I did build my second Airship commuter pier module. In that very moment I experienced the massive lag again, on all sessions of my current game. As soon as I removed the commuter pier module it restored immediately. I tested it several times, but it was always the same result, as soon as I build the airship commuter pier on my second island the game performance dropped and the RAM the game needed increased by ca 10%.
Did anyone else experience that?
