Bug: Can't discard a rune while on rune reward window

[Hoja Lateralus]

I had all rune slots filled and got into an elite (or rather super elite? I dunno how are those called) and can't accept new rune because all my slots are covered and it says "Rune slots are full! Discard a rune first", but I can't, right clicking on my equipped runes does nothing.
Version: today's update

Yep same here. Happened to me today. Before the update I could discard, after the update I cannot.

[Glockenspeal]

happened to me as well

[OMGalvatron]

just happened to me as well.

[TheLukerAbove!]

Same, missed a legendary rune because of the bug.

same for me, as well as runes I buy in the shop not getting added to my bar
