Freeze on next turn loading

hi, i just bought the game with the dlc on steam.

The game freezes after i click next turn, in the loading screen. My steam is in french, most of the game is in french too but i believe the dlc are not. I did not install any mod or alter the config. Playing on win7 x64 home. I’ve had to kill the process after i hit the next turn button, the process is not responding.

My save is “Canadian”, checked the tornado and earth quake rest is default.

Usually freezes every 2 turns.

edit : switching game to english instead of french solved the issue.
