As per the picture, the icons are mostly visible but on the odd occasion you'll get one that doesn't show even though i knew it was there. Also happens with the no resource available tags/flags.
Steps to Reproduce
Just playing through and tagging items for deconstruction or running out of a material; its speratic and doesn't happen all the time. I've only had it happen 6 or 7 times on different play throughs.
