b) It's the persistent charges bug again (likely). However, whenever this has happened, I don't see the combo carried over but it does functionally carry over as I get the combo bonuses at the start of the fight.
What I've been doing to "fix" this is clearing my phone's memory cache. This also works for Corvus, because I've noticed his charges aren't always added. When I clear the cache, I log back in, and they populate. Hope this works for you.
The team is aware of this issue and has a thread going where we are gathering information on it. If you can share the information requested here, the team can add that to their date in their investigation.
