I could not reproduce this, tried with id missing and duplicate id names. And yeah the others are some bad design decisions for the editor that waste a lot. Every attribute on a node even generates element data that has to be synced with all clients, which makes the map downloads even bigger. write an admin application please, this server is in desperate needs of some brain. Not seeing how this is related, but ok wasnt a stab at you or anyone, just sayin you could maybe use some help with the server
