Daily bump.

This has nothing to do with PC specs (though I imagine lag itself would exasperate the problem further on older PCs).

Intel i5-4440 Haswell, 3.1GHz
Gigabyte GA-Z87-HD3
Gigabyte Overclocked Geforce GTX 650 Ti, 2GB, GDDR5
32GB of Corsair Ram
Windows 8 x64

Still get the problem running on both high and non-existent graphic settings.

Now back to reality, still no acknowledgement of their problem. Starting to be like a broken record! My friend (also in New Zealand) encountered a party of Aussies trying to do Titan HM last night, it was a duck shoot for Titan - everyone kept dying due to this issue.
