Mercenary textures show up as error textures when using Vulkan

[Peels]

Describe the bug

When I try to play while using the -vulkan launch argument, the mercs become a red mess.

To Reproduce

1. Right click s&box on steam
2. Click "Properties"
3. On the launch options, type -vulkan
4. Start the game and join TF:S2.

Expected behavior

The mercenaries should be properly recognizable, yknow, have a face and such.
