Cant create control groups. been a year

meele is unplayable, how is this still an issue after a year?

You need to be more elaborate. First time I hear about this. What I do hear is that sometimes actions do not register and although that is annoying, it is by no means the same as being unable to create any control groups. Are you playing on a laptop? In that case you might have to use ctrl + fn + 1 to set a group, rather than just ctrl + 1.
