hackable crate fell on the combination lock and there is no way to open

That can happen as it is just freefalling and bounces around. You can try adjusting the settings for it under the drag and weight

thank. I'll try

I added in those functions as requested to give the drops more life then simply just falling to the ground and being able to have control over how they react. Trying to find a Key balance all depends on the other settings as well, Plance Speed alone plays a huge roll on how the Paratroopers and crates react with the physical elements.
