It would be nice if you could mine the crash site using your pick axe for iron plate, copper wire, circuits, etc... Currently you can only shoot it to get rid of it.

It has other way : crush by car. (lol

In this mod, I used the official object simply. it is official behavior.
Also, I think that this is for decoration of map than resources. therefore, I didn't think for removing this...
Thank you for idea. have a nice game!

When disabling ship wreck in Mod Settings before map generation i get this

Error while running event TJQuickStart::on_chunk_generated (ID 12)
TJQuickStart/control.lua:41: attempt to perform arithmetic on local 'distance_max' (a nil value)
stack traceback:

Ouch!
Thank you for reporting. I fixed that.
Have a nice game!
