Crash draintestns.dds hash isn't in sync

I'm having problem loading the game with one of my characters:

Exception
"Art/Textures/Environment/beach/draintestns.dds": Failed to uncompress texture file

Running PackCheck.exe temporarily fixed the problem. I could log in as another character.
When starting the patch dialog appears.
Output from PackCheck.exe.

Checking pack file Content.ggpk...
/Art/Textures/Environment/beach/draintestns.dds hash isn't in sync. Repaired.
/Art/Textures/Environment/beach hash isn't in sync. Repaired.
/Art/Textures/Environment hash isn't in sync. Repaired.
/Art/Textures hash isn't in sync. Repaired.
/Art hash isn't in sync. Repaired.
Done.


The problem returns when I switch back to the other character.
The game has been running fine earlier today.

I managed to solve my problem. I renamed the ShaderCacheD3D11 and Minimap folders, then reran PackCheck.exe once more.
