GenerateCombinedDynamicVisibleListJob crash (Shadowculling.cpp?)
Several users are reporting an access violation crash in the 3rd level of our game. For those experiencing the crash, it seems to be intermittent to 100% reproducible.
...The problem we are having is that we cannot reproduce the bug at all on our machines. The crash doesn't happen at the exact same point each time, but they are all within a few minutes of each other.
From looking at the minidump files we've been sent, the crash always occurs on the same instruction:

I seem to recall that GenerateCombinedDynamicVisibleListJob(CullResults*) was a part of shadowculling.cpp.
Does anyone have any more information / know of a workaround to this problem?
Many thanks for your help.
