Oddly enough, I JUST had this issue crop up, as well, using Shantia's Face 2, twice, on an Elf. I played through this part this morning on another character using all the same mods except this one, and it played right through no problem.
This morning (ok, yesterday morning, now) I was using
Black Silk Attire
HD Eyes By Zachillios
Josie
Josie's Outfit (makes her gold cloth pink)
Pajamas Silver (Kamael's jammies)
Patch_nolevelreq
Remove All Armor Class Restrictions
Solas Pajamas (Kamael's)
Today I added Shantia's Face 2, and got stuck in the War Room at Haven, just after the first scene in there. Got a REALLY LONG load screen, then when it finally loaded, I was still in the War Room, but the doors weren't interactive, and there was nothing on the table (no map, no clutter.) I also never got the scene with hammering up the announcement of the Inquisition, or me on the steps with the Advisors, or the "Dragon Age: Inquisition" title screen.
I initially thought, since I walked into the War Room in my jammies (for screenshot purposes with Kamael's Silver jammies) that it was having an issue because it expected to "replace" whatever armor I was wearing with the Scout's Coat. So I put on my Mercenary Armor, and tried it again.
I ended up swapping out the merged folder for a fake patch folder to get past that part. Sounds like I'm in for further problems, though...
