There are 2 hidden switches, too.
One of them opens 2 of the compartments but the other one does nothing.
I checked in DLE and found this:
Cube 215, Side 1 = Trigger 12 -> opens access to cubes 221 and 222
But Cube 210, Side 1 is no trigger (although having the trigger-texture)
So access to cubes 219 and 220 is nowhere to get

Intended (to nag players
