I just got my first Gorseval kill today and went to the vendor to see what unlocked. Trinkets. Trinkets are what unlocked. Everything else that said it should unlock after defeating Gorseval is still locked. Not a huge deal to me, since I couldn’t afford any of that stuff, but still a real problem.
This was not unique to me, as the two or three other people who got their first Gorse kill in the group have the same issue. We all sent a report through the in-game bugs in one way or another, but it didn’t seem like there was a category in that system that this fit into.
