Can't take Wrex to quests in Citadel DLC
I am playing the Steam version of the game, on Windows 10. No save files have been modified. I have the following mods installed via ME3 Tweaks Mod Manager, all fully up-to-date:
- LE3 Community Patch and Framework
- Expanded Galaxy Mod (core only)
- Cerberus Retrofit
I am doing the Citadel DLC. Wrex is alive and the Genophage was cured. He joined me in the first mission of the DLC, and is present in the apartment and in all apartment cutscenes. However, when the game cuts to the squad selection menu before leaving on a quest, Wrex is blacked out and cannot be selected (see attachment), just like EDI was for the casino (though for EDI this is explained in the dialogue). There is a "select" button there if you open then close his info menu, but clicking it does nothing, and neither does double-clicking his silhouette. This happened before the casino mission, and now is happening with the archives mission. Restarting the game does not change anything. I wonder if this bug could possibly be related to the additional squadmates feature in EGM, even though I haven't installed the Normandy module that enables that feature.
I found an old thread from 2013 that appears to be about essentially the same issue, but it does not contain a solution or any insight as to the cause.
Update: I validated the game files, and it did not help.
