[2020] Daryon vs Myrna too hard?

Originally posted by zahk.lightsbane: After the update today, the fight appears to be bugged, but easier. Myrna now doesn't leave your party, and you have her (and Selene) on your side fighting against herself? She also doesn't leave the party afterwards. Submitted a bug report on it.

I have no repro in editor for this bug but you're not the first to report it, can you provide me your save (before the issue started) on the EOE discord (Kaldorei) please?
