@ragnar-l_odbrok Thanks for your post about this! I understand you've not been able to use weapon-specific finishers or gallop since the update, which is very unusual, and I'd like to investigate.
Can you start by running through our troubleshooting guide for me? In particular from that guide, please make sure you've updated your graphics drivers and operating system, you've verified the game files, and you don't have any unnecessary background programs interfering with the game. These steps will make sure that nothing went wrong during the update that might have corrupted any files.
If the problem persists after those steps, please let me know - I'll have some further ideas in that case It'd be great if you could describe what happens when you try to perform these actions - does something else happen, or nothing at all? Thanks!
