What the code is doing is rapidly adjusting the loc var of about 300 client images in tandem with a camera eye's movement.

EDIT: found the instructions. Here's the WinDbg log.

Hanging with images seems to be the same thing as the bug I thought I fixed that MrStonedOne reported. However the cause of that hang should be quashed, so I don't know what would cause yours. Unfortunately your stack info doesn't appear to be on the right thread and isn't giving me any useful details about the hang. Do you have that dump file?
And short of that, do you have instructions on what exact SS13 build to use and how to trigger the bug? Since you can reproduce it reliably, I may be able to zero in on the issue myself.
