This is the second time I buy the game because of similar bugs !!! I thought buying it on steam will solve all problems.
Kilgore is locked and unplayable for me on Steam version. I can confirm others are complaining from same issue on steam forums.
I think I identified what’s causing the issue, so it will be easier for devs to solve.
Some reported that it was solved by verifying files integrity n Steam, which downloaded for them some missing files, this did not work for me, but I checked a folder called “PAK” in the game local files, and I found files with the names of all characters, excluding Kilgore, so I think missing files are causing the issue.
