Priority: Horizon Bug [pc]
OK, so maybe someone here can help me with this. I'm re-playing ME3 and just got to Priority: Horizon. However, every time I start the mission, it's like it's already been played through. The Cerberus shuttle that's supposed to crash at the very beginning is already there and no enemies show up. This isn't really a big issue until I get to the part where you're supposed to drain the pool of water. I get there and the water's already been drained, but the door remains locked, preventing me from progressing.
I've been searching for a solution to this problem for quite a while now, but the only bug anyone seems to run into on Horizon is the door of death one. I also tried restarting the mission, doing the mission at different times, and reinstalling the game. Nothing seems to work.
I am using a few mods, but most of them are HR retextures of squad mates and Shep. A lot of these I've used before and haven't experienced problems with. I've already tried starting the mission without any of the armor/clothing mods I have installed, and that did absolutely nothing.
Anyone have any ideas as to a fix for this?
