Explosives Delivery contract doesn't work as intended

I just typed out an entire in-depth bug report for this and sent it off, only to be informed that it didn't send because I didn't confirm my email before sending, so now that's lost in the ether and I wasted my time, so if this seems brief that's why.

Anyway, to get to the point: The contract pays a total of $200k but costs a minimum of $2m to complete. You have to pay for the crates (4 of them) at nearly $250k each because they're full of solid fuel which you can't empty out of them and have to pay for. This also makes them weigh over 500kg each for a total of over 2t. These two factors combined mean that you're guaranteed a huge financial loss for doing this Progression contract. I don't think that's intentional.

It's frustrating to do a mission that requires slow driving to avoid bumping off one of the sharp edges of the ridge-ridden triangle-based terrain - likely saving/reloading several times and even restarting the flight because when you reload the crates, being seperate to the vehicle, have reloaded in a different position and bugged out either breaking your vehicle or pinging up and exploding on impact - knowing the whole time that you're guaranteed to make an enormous loss on completion. It's just not fun having to do this for progression.

It's hard to get a relevant screenshot for this so here's the vehicle in the designer with one of the crates I guess.
