[PR] Gravity and Gravity Tethers

[glowbold]

I get stuck in corners of rock floors while mining occasionally even when wearing magboots and have to throw a rock in order to gain traction again. It only happens sometimes though... Let me know if examples would be helpful

It also appears that Oshan cargo doesn't work anymore? Not sure if that's due to this change

Just pushed a fix for Oshan.

Best thing to do is file bug reports in the top-right corner when these things happen, whatever info you can provide can help track it down even if it's not a full reproduction.
