When you hide a unit with the hide module, the unit will still be visible on the radar, causing hostile AI with a radar firing endlessly at the position of the hidden object.
hideObject and hideObjectGlobal will also leave the hidden units visible on the radar, but hostile AI won't fire at them.
It would be great if hiding an object with any of the available methods would make it invisible for radars too!
BONUS:
Is it intended behavior, that the hideObjectGlobal command does not work in the editor/ SP, while the global-counterparts of other commands do without any problems?
