I am having difficulty reproducing the Summery tab and the Character Sheet tab mismatching with RC3.
But I have certainly encountered it.
The rolled hit points and the Encounter hit points mismatch on the Summery tab this time.
Here the Summary Encounter and Character Sheet hit points match at 24,
but they don’t match the rolled hit points at 26.
