Re: Sentry gun doesnt level up (boris tier badge) during solo play vs bots

@Zakos-DK @Myona_B I found this to be true across the board as well. I have only been able to level up to tier 3 in solo/co-op. It was this way for all badges that I tried to tier up. My sentry gun stopped right at 18,000(T3), and then continued to accrue in PvP as Zakos-DK says.
Keep in mind, you don't get any credit for images and tags objectives in solo/co-op. Those are all PvP best I can tell. Just the badges to T3 in solo/co-op.
