After firing a weapon, removing the master computer and then undoing will reset its cooldown. This could be used in combat with the undo/redo buttons.
A possible fix would be to lock a computer down when it is reloading, so that you could not delete it by hand or through the undo/redo buttons or just edit it in general.
A part of the community knows about this exploit since it has been shared in public chat before...
How to reproduce:
# place down a computer, link it with some modules
# link that computer to a damage pulse system so your cooldown is longer
# fire that weapon, delete the master computer and press the "undo" button
# you'll notice that your X second reload has been reset completely.
