Overkill seems to have broken most HUDs with the april fools update.
There is the lua fixed for WolfHud.
The fix was found here, i'm just uploading corrected files so people don't have to patch this themself. Thanks to chrasse for providing the code at: https://github.com/Kamikaze94/WolfHUD/pull/919/files
the lua folders goes into PAYDAY 2\mods\WolfHUD-master
