kaigon,
tried 1419 scenario and it played just fine. no crashes, tried various speeds, placed merchants, declared war, disbanded troops, etc.
however, playing 1559 scenario was MUCH less stable. didnt even get out of normal speed. btw i am using earliest version w/ latest beta patch, 23rd.
playing as bristol, my first crash was sept. 1559 while fighting battle in bristol w/ wales (was also at war w/ lincoln). reloaded to may b4 war. built troops, placed merchants, crashed again oct.
reloaded to b4 crash oct. this might be most interesting, no one declares war on me, of course most other countries at war, getting anexed etc. i prepare to att midlands, however, game crashes exactly nov 30. i reload to early nov. game crashes again nov 30. reload, game crashes again nov 30. it doesnt crash the instant it hits nov. 30, it crashes the instant it should turn over to dec. 1st.
hope that helps, but it seems 1559 scenario is unstable. and there is no getting by nov 30 it seems.
