Now I uninstall Ascension and Tactics, and left only BGT-weidu mod.
I didn't find ar0602.are in the override(only AR0602.BCS) so I didn't do anything.
Then I installed Tactics again, ar0602.are appeared this time and the game crashed.
After that I renamed the ar0602.are to .bak and restarted a new SOA game and it goes normal this time!
Does it mean that the trouble is caused by Tactics?
However, I remembered in the old BGT-weidu version(0.x ), I also used this mod and it has no problems...
