Summoned Monster ID: 8510000 Pianus and crashed

[LuneArk]

Game crashed after using "/spawn 8510000" on the left side of the first map on Maple Island. I can get past the channel select screen, but once the character appears in the map, it crashes before it can even land on the ground. Probably not a channel crash, but a map crash that traps all those who are in the map, or even enters that map.

Data.wz related, need to update the client wz, the server thinks pianus is a valid mob because it exists in Data.nx while the client has no such data
