Seems like all you have to do is change whatever button to the actual numbers.. seems like the game only registers 1 2 3 4 buttons. For example I play with my mouse a lot. so i changed the buttons "Forwards" and "back" or "mouse 4 and mouse 5" whatever you have it under, to the actual number...
i ended up changing my mouse buttons to the number 4 and 5 and seems to work so far.. well i tried against a bot match now im gonna try an actual matchmake. ill let you guys know if it helped
SIGH literally me.... my fingers get all confused when i try to use 1 and 2 too much. specially when a lot of things are happening. so it helps if i usually keybind videos to mouse 4 and 5 but yes it keeps bugging.. very upsetting..
