Attempted to retry map "Somewhere in Antarctica", which appears to use +frozend (I'm pretty sure it said 'industrial' on the load screen).
The first load went fine. NASTY little fight, loaded the two dropships practically on top of each other, but went alright, but didn't like one of my losses, so I 'retry'.
Below is the failure from the console log. I did not get an assertation failed message. I can give you the full log if you need it.
