For comparison sake, here are excerpts from my logs from yesterday and today.
Upon entering Valhalla, KoLMafia set
Preference timesRested changed from 1 to 99.
Later, upon exiting Valhalla, it set
Preference timesRested changed from 99 to 14.
Normally it would go from 1 to 0 and then be correct following the ascension. The order of a bunch of property resets changed between r25765 and r25773. Attached are the two logs of properties resetting upon reaching Valhalla named PropertyReset11 and PropertyReset12 based on the date of the month. Diffing the two files can give you an idea of what went wrong, though why it happened, I have no clue.
