The last 2 weekly challenges (Cranium Cracker and Tiny Terror) haven't registered as being completed. I completed them both on Solo as a Berserker on ZEDs Landing. This isn't the issue of not get the reward straight away as on the front end on the weekly challenge sub-menu, the reward item isn't ticked. Also I did receive the Trophy for completing a game Suicidal difficulty (applies just for Tiny Terror).
I have YouTube videos show the challenges being completed. I can post links if needed.
