I cast a spell this morning. It promptly backfired so I quickly reloaded the page (which often has the effect of cancelling the last action). My PC's a bit dodgy sometimes and it froze for a while, so I got a shower and when I came back something a bit odd had happened: the backfire was still in effect - Portals had been reduced by one - but the mana was fully recharged. Weird. So I went to work.
I just got back, had a quick look and my spell count is now at 2. That's all-time spells cast: 2. I've still got the achievements I earned as I'd been way over 3-4,000 but I was wondering whether anybody else has noticed that bug? I even did a quick ascend just now in another window to see if it would rectify after that but nope: spell count still 2.
