This game unfortunately crashes for me in Firefox when I try to leave the Options screen, saying "Security Error. The operation is insecure". It refuses to save as well. I think I had the same problem with your otherwise great games from the Medieval series as well...
Your game unfortunately crashes when the network is unstable while it tries to load new data. Maybe you could change the behaviour to retry the download instead of showing an error message and freezing? Anyway, I really love the game and its dark humour so far.
Whenever I try to leave the options screen by right-clicking anywhere, I get a "Security error - This operation is insecure" text message in the game and it becomes unresponsive. Any ideas what might be wrong?
