DX11 crashes in Sirensong Sea

[Wyxmir]

I've been fine in Stormblood so far to this point. Levelled RDM 50-60 and now doing content. Everything was fine until the first boss fight started in Sirensong. Got this crash 4 times. After the fight was over crashed again on the way to the first trash pull after the boss. Got my friend to kick me from the dungeon as to not waste anymore time.

System: Win7, AMD Radeon R7 200 series, 16 GB RAM, AMD Athlon X4 860K Quad Core 3700 Mhz

Will attempt again with a group and see what happens.

EDIT: yep still happening.

EDIT 2: If I walk backwards through the first boss room and face my camera the opposite direction it'll last a bit longer into the dungeon but I will still crash. Something is rendering and my DX11 doesnt like it.

EDIT 3: Whatever it is, it is only in the second part of the dungeon. I could take the shortcut to the third part and proceed just fine with no issues and complete the dungeon. My friends are telling me it's probably the ship graveyard with the glowing boat.
