I am building up a jack of all trades char, currently he is level 18. Today I went online and played engi, something was wrong because my key binds for kevlar and turret had swapped round.
I thought nothing of it. Then I switched to soldier to find I had the scavenge ability which I know I have not purchased on this char.
And then to confirm that something really screwy is going on, I see this,
How on earth do I have a lazarus? It even works!! Not to mention the fact I know I have not selected the other abilities too.
