[Crash] Many crashes, most approaching base [40062]

Tinysquid

I'm having significant stuttering/crashing, particularly when approaching my base, although it can also happen when diving elsewhere. It's gotten noticeably worse as I stockpiled more things in lockers. This is my first game, and I only started playing a few days ago, so I'm not talking about a huge base--it started when I had a single corridor with a couple of lockers in it.


Here's the requested info, with the most recent crash log: http://pastebin.com/Kxp6sP6B
