car7, before you do anything else, try this:
Start combat, push end turn. When combat mode ends try to talk to Myron again. If he won't, try to start combat a couple of more times.
This should work if the bug is the same as I think it is, ie that combat ended while Myron was unconscious and now the game treats him as if he still is.
And as always if you want help try to give as much info as possible, it makes things so much easier for us.
