I seem to have lost several days of upgrades after the server maintenance. Had a gold (evolved) No Egrets parasol who was close to maxed out on upgrades, and upon going back through character list to re-apply moves, noticed I’d lost most of the last tier upgrades I’d purchased, as well as the skill points used for the upgrades. Maybe 2-3 days’ worth. May have happened with others but haven’t gone thru the whole roster yet. Anyone else have the same issue?
