Version 3.5.6 is out with some old bugs fixed and some new bugs created. Getting closer to considering spell timers done enough for now. Nearly at 50,000 lines of code and config - please let me know if you run in to any bugs, they are definitely out there!
As an aside, apologies for anyone that endured hearing `that was nice` every time they received a light healing spell using the previous default config - I thought that was a suitable notice for a non-torpor heal over time spell expiring but turns out it's a more common output line than I thought and should now be disabled by default.
