>it looks pretty intimidating
good.
the duper is absolutely capable of blowing itself up if misused. and also everything around it. aside from the sand/concrete, it also dupes like 12 tnt/sec, so that would be a pretty big boom.
also, since it creates ~150k concrete per hour, its capable of lagging the shit out of the server, possibly also crashing it, if its left running without the items being collected or disposed. items take 5 mins to despawn, so from a 150k/hr duper, you could end up with more than 10k items just sitting around waiting for the despawn timer
the storage at least should be pretty resilient to abuse, but still, it'd be better not to test that if possible.
anyway, yes, instruction books incoming. and don't worry, operating with 2 players is pretty simple, and pretty unlikely to result in explosions or server crashes.
operating with 1 player is much more involved, and actually can result in explosions or server crashes, but still not rocket science. just takes longer and requires a couple round trips to the end and the duper to do all the steps in the right order.
