Somehow while leveling up a glyph after completing a nightmare dungeon. UI freaked out and only saw the glowing animation for a legendary node. Closed UI and opened again (pressing A). Same thing, no board, legendary node animation showing. Tried a third time NOW I see only the starter board. All paragon points refunded… But ALL GLYPHS HAD THEIR LEVELS REMOVED!!!
It seems the UI glitched out and I lost the XP points from that one nightmare dungeon. Completed another nm dungeon and got the XP points and in that UI all the Glyphs show the levels on them. But the paragon board UI no longer shows levels on the glyphs.
