I'm playing EE with patch 1.5 I can't use this mod. WHY?! The move forward options show up in the Control Options. But they both make Geralt run!
WHYYYYYYY!? SO IRRITATING!
TW1 is now a legacy title, and it will likely not function exactly the same on a modern OS and hardware as it did back when the game was current with hardware. Your best bet is to contact the mod author about the issue. If they are no longer available, you'll need to post your issue in more detail. Include things like your system specs, mod list, load order, etc.
