Just a minor bug that's been bothering me for a while. I'm sure I'm not the only one to have seen it, but I searched the forums and didn't see anyone else making mention of it nor have I found a topic posted here about it. So, just for good measure, I made this topic.
Anyway, as you can see from the screenshot below, the description for the KV-1 in the Rewards tab is missing and currently set to "BLANK".
