UPDATE:
With the latest beta build installed it seems to be a bit better. Less frequent Keyboard issues (hot keys not working) though it does still happen.
I’ve been able to reliably ALT+TAB out of the game as well, so that’s no longer an issue.
Re-naming Mercs is a bit wonky though. I can’t delete more than 1 letter at a time. I have to delete a letter, then save, ten re-open, then delete another letter, then save, then re-open over and over to rename say Bjorn to be Barney. Minor stuff I know but still.
