Hi, First of all great job with the game.
Warlords Dos games can be extremely buggy so... this runs quite well.
So the error I am seeing is " Target has changed ... are you sure you want to continue". However the sync or the server ? causes the entire questionable area IE: city or gold production to be "non-targetable" and in one case locked up the game causing a reboot and cascade error on the graphics sprites. NOTE: that game became unplayable and I had to surrender. It might be more prevalent in simultaneous turn games.
This error has occurred in the tutorial twice and in one game many times.
Thought you should know,
