Going again through the code, I see the number of chunks is less than I previous stated. If the

`fragment_chance`

is true for a ship, the ship first generates fragments with role "wreckage" with the number of n_alloys. This wreckage is only short living (< 1.25 seconds) and has the size of the ship itself. This "wreckage uses up the alloys, so when the "wreckage" is generated, the n_alloys variable is lowered according:
Code: Select all

`n_alloys = ranrot_rand() % n_alloys;`

As a test I exploded some traders, while logging the n_alloys variable based on mass and the value that Oolite is actually trying to add.

Code: Select all

It smells like the seed is reset to the same value every time this part of the code is entered.
