I've just mentioned this in the comments, but a lot of the challenges feel a little too easy when I run tele/drone with the default map sizes. I think maybe a good solution would involve restricting one of the following elements: map size, tele, drone. Like you can have tele/drone but are forced to huge size. I've just run the challenge with huge items but my drones picked everything up anyway, I was expecting them to not to. I'll give some more feedback as I think about this.

Thanks for the idea. There are multiple issues with the challenge : if you have drones, it's like a normal map, but if I make resources not carryable by drones, then it's a huge disadvantage if you chose drones in the first place.
