As per title, if you are dead and in spirit form and you try to pick up some money on the ground, it will make you drop all the money in your inventory.
Just happened to me, on the action server, lost 6547G. I suppose it can happen every time.
I dont think the location is relevant but it's on Lysaga hills.
Ideas: I suppose there's a lag between the action of picking the money up and being added to the money pool, and then dropping them all on the ground. Further attempts to pick them up fail.
edit: performed the @debug command.
