Is this something I can report people for?

I believe everything in your personal room that can be picked up once set down will be at the housing enthusiast or one of those other housing npc (not sure which one since I haven't had the need to do that yet lol). The stuff inside the FC housing is for the FC once placed, so unfortunately I don't think there is much grounds for that.

The 300K is never recovered though. (So your carbuncle lamps if in your personal room is probably at one of the npcs in the district).
