Start a fresh game
1)Alter casus belli option to 21 Diplomats, as mentioned in other threads.
Leads to no more wild wars between the mayor and important countries.
Leads to none but the scripted wars and the most ctd happen, cause the script crashes with the reality, that this or that country is occupied by now.
Austria owns most Italy, Germany occupies Belgium and so on - you know all that.
In fact there is no reason, not for player, nor Ai to come to peace terms with the beaten country again, since one can exploit the victim totally and indefinitely.
The most of the rare clashes of that time are anyway scripted by data.
2) To relax your nervs alter the value for General dies of.... to anything else but 1, but only after the initial round to get the plus generals.
Leads to no more generals die and are created.
There is rumour, that the number will rise when the armies grow bigger, but at least till 1860 play with the original generals to get rid of the frustration to see them die like flies. Then check again for a while whether the situation gets better or worse by switching back to the value 1.
The execution phase of the game runs much faster, and runs with no more ctds at the end of the script addition at the very end, that is responsible for all this balagan. I had not a single crash playing one year time and a fast running through the execution phases.
The game is in the beginning somewhat more boring or less exiting, but for the many building style players that could be a benediction.
