'It would appear the 1:50 cycle is not based upon time played, since mine would have been 64hrs 10min if it was. '

I based my calculation - rough calculation as said- on actual, real-time measurments, no resting bench or alike:

1. I visited Ward of Regret and looted it.

2. Then visited it every few minutes to spot the respawn moment (accuracy +/- 3 minutes that's why I've written "rough").

3. Then looted respawned chests again as soon as they appeared.

4. Then again was visiting Ward of Regret every few minutes to mark the respawn time.

BTW I have a suspicion that the game calculates respawn time based on time spent in the DLC area and doesn't take passage of time in Gransys into account.

I did just have 2 Garm spawn in the middle of my boss fight with a Gorechimera 

was Gorechimera in active combat for sure (and eventually was the battle theme was playing?) when Garm appeared? Large monsters at BBI tend to lose focus off the player in certain places even when attacked! I could mention tenths instances when I was not only attacking but also attacked by some enemies yet the game wouldn't consider me as in battle and I could save no problem.

It's kind of easy to witness this at MIdnight Helix or Duskmoon Tower when fighting some dragons as they fly around and often go out of their aggro range. And it takes just second of "peace" for the Rancid Bait to kick in (I recorded it btw).

Would you mind checking if the game disabled saving next time the necrophage spawns mid battle?
