Need help removing a block through console

so I've got the position of the block in question from crash logs, but when i try to delete it in the server console with "setblock x y z glass destroy" the console kicks back "that position is not loaded"

as it is, an ender tank has messed up in the group's base and is causing crashes whenever a client tries to load in the area... is there another option that can be tried, or a way to get around the position is not loaded?
