Turn based heals are sometimes still not working correctly.
It seems if a hydrosophist casts a second heal during the last turn of a previously cast heal, there is a chance the previously cast heal will get cut short.
Here is how I've been replicating the issue:
Scarlett casts Strong Regenerate on Roderick
Scarlett then casts Minor Heal on herself immediately after
Roderick only receives one heal from Strong Regenerate instead of two.
It almost seems that if the second heal gets cast too close to the last "tick" of an existing heal, then the existing one gets overridden. I'd imagine using Cure Wounds instead of hydro spells would have the same effect but haven't tried it.
I've run into the same thing casting minor heal twice in a row. Nice catch on the particulars about how it happens.
