[0.17.1] Exploit in early game

[nafira]

This one is pretty simple :
If you hold Coal in your hand while picking a big boulder, it gives you 20 stones AND 20 coal (it's also bugged in the display section).
So with 5 boulders you have 2 stacks of Coal ...

Thanks for the report however that's not an exploit. The large rocks give coal and stone.
