Reliquary Crashes Game with Error on Screen

When trying to enter the Reliquary, game crashed on loading screen. Multiple errors appeared, beginning with:

Exception
"Art/Textures/Environment/interactables/UniqueStrongboxes/Vase_colour_DXT5.dds": Failed to uncompress texture file

I tried with my DeadEye and had to cont/alt/del to end the game. Other areas loaded just fine.
