[Some bugged "Excalibur" on Progress&Rewards screen]

I have been experiencing this exact same bug throughout the weekend — as have a few others apparently, according to a quick little search. Some friends in-game have also brought up mention of it happening to them. I'm not sure whether this is a placeholder for something, or just a genuine issue with the UI spitting out some error.

I took this screenshot last Thursday, when I first noticed it:

It also seems that the rank progression always remains the same for everybody. This has occurred at least three separate times for me so far, all on different missions and using different load-outs.

Hopefully DE will fill us in on what's going on here.

[Tenno Tunes Vol 4 Contest [Winners Announced]!]

Awesome to see that people have already begun submitting their work! Can't wait to see the creativity that comes out of people's minds this time around. I loved what Tenno Tunes Vol. 3 brought to the table, which makes me super excited for what makes it through to be featured in Vol. 4!

[Why do you keep playing Warframe?]

I started playing during Closed Beta, but lost interest pretty fast, and then just simply refused to touch the game, as I felt it didn't have much to offer. Fast forward to January of this year: I was struggling to stick to any game that I was currently playing, and was craving for something that I could just go on and grind. Noticed that quite a few of my gaming buddies were hammering it out on Warframe, and decided to give it a go again. I'm glad I did, because I did not realise just how much existed in Warframe. I came for the grind, stayed for the lore, customisation, as well as the overall community. Definitely risen to becoming one of my favourite pastimes, that's for sure. Just wish I did not neglect it for as long as I had. I can see myself sticking around from here on out, though.
