I installed 3.19 and started a new game using my custom mod. I played no problems to turn 150 and then opened worldbuilder and the game crashed. I traced it back and the last good time I could open worldbuilder was turn 127. By rebooting my machine after each turn I was able to continue to open worldbuilder until turn 130. What is the problem? I have done a complete uninstall and I am re-installing using only the latest patches and will try again, but my inital impression is that 3.19 has a bad memory leak and 3.17 is more stable.
Alot of MAFs with 3.19.
