I know this happens because of a bass attack. I had an earlier save when it happened and when I reloaded the attack happened later and i lost sight of the battleship but I am pretty sure it is the same thing.
"A fatal error has occurred: code 0xc0000005"
attached save and log file. I updated to the lastest nightly and tried some of the opengl suggestions i saw in crashes with similar error reports. So far nothing has worked.
