They changed the reward from the second event from Rev-01 upgrade kits to Rev-01 parts, which saves everyone who already used the extra set of Rev-01 parts from Resonant Synergy to upgrade their first Rev-01 to Gold II (which would have made an extra set of Rev-01 upgrade kits useless to them, and left them unable to rainbow their Rev-01).
The ST upgrade system is still obnoxiously confusing and way too easy to screw up, and I would like to see them rework it, but at least they recognized they'd created an issue here and addressed it.
