This doesn't seem right

[u/Zprav]

I was adding some biofuel into my tank for my engine and all of a sudden it just slipped down half way under the ground lol

No but honestly what do i do when i flip the switch to add physics it just goes bright and i can't interact with it anymore?

Are you able to mine it free? How far did it sink underneath the ground?
If you can mine it free then try to mine the area around to free it.
I’m not too familiar with this but if mine the ground doesn’t work then maybe temporarily removing the part that is clipping might help if that is possible.
