Not sure where you're looking, but I count 310 HSP in the next Union event. Did you use the backup feature, like I instructed, to collect information from event pages prior to their revivals?
Also, for context, Morrigan was introduced around 11/7/16 in the DMM version, with Shingen following around 1/30/17. Subtract 1.5 months from (or add 10.5 to) those to approximate when they'll be introduced to our version.
