I've got this on normal mode. Pretty annoying. tried to load back a save, but the autosave overwrote it. the resistance leader starts walking again when you get near of him, very slowly, and reaches a point in the map, then loses the left limb(???), and i can't talk to him.
Another nasty bug was that when i did a load, somehow the save corrupted and i went to level 1.
PS: I'm on PC.
I've attached the pictures. Latest mass effect too.
1st pic: leader missing limb and no interaction
2nd pic: leaving area, leader and marker vanishes from indicator; arriving close to the point, leader respawns then slowly starts to walk towards the fire
3rd pic: a bug that corrupted the save, and reset me to lvl 1(there's no way i could be level 1 on voeld, if you are wondering); i tried to load a save that was before the leader bug, and when i did, i got returned to tempest, and had my level reset. I get a autosave when i load the level, so it overwrites older saves.
