Disregard - Time and Faith/Smite - Broken Interaction?

I’d swear this was working correctly last night before I went to bed. This morning I noticed my mana level slowly going down over the course of a zone. I started paying attention during fights, and it doesn’t appear I’m getting any mana back when I use smite; if I switch to rive, I see my mana visibly go up in the mana globe. Both rive and smite are 0 cost right now.

Disregard… I’d swear my mana globe was staying full before I went to bed, but I just looked through all of the skill nodes and realized fissures cost 10 mana each and I can do 3 per second… Maybe I just got lucky with pack density or wasn’t paying attention after upgrading my wand (old one had mana regen on it). Everything works as expected if I reduce the number of fissures and watch for hits that don’t produce one.
