When a silo is loaded manually (by the player or by an inserter) and the option to accept orbital requests is unchecked, the rocket will launch automatically if a platform requests an item and the silo is full with that item. This can be useful in some cases.
Here's a problem: a rocket can hold a maximum of 300 processors, but when they're loaded, they only represent 999/1000, so the rocket doesn't launch and everything is blocked
