Please don’t hang Me, just a thought.
How about making your character slowed down like in crafting mode while holding foundations, stairs and other things that are needed to build a base?
it’s pretty unrealistic holding 10 sets of stairs (I know its a game, just saying <3)
I mean the only reason you would run around with that kind of stuff is to skyraid.
Anyone who is building a base crafts the materials and puts them up in the next minute after they are completed.
Also if this would have to work the airdrop loot might have to change to raw materials, or just make it harder to run away with the loot making people work together defending the courier.
this would of course not be a priority to the devs, they are working on more important things right now
