Yesterday evening i swapped out glyph of imp swarm at the beginning of the evening.
Later i wanted to put it back in. The glyph was applied, but no new ability showed up in my spellbook.
The ability icon usually even comes onto my actionbar each time i put the glyph in (and it annoys me)
But this time, the only thing in my spellbook regarding imps is the usual passive ability (when you have no glyph).
Do you see the same thing or do i have bad luck ?
