I had this on my old PC which was 3.2 Dual Core with GTX 260 Video Card 784mb 64bit Vista and 8G of RAM. The weird thing is I would see it sometimes very soon in small battles.
I have not seen in yet on my new PC which is 3.4 Quadcore with GTX 670 4GB 64bit Windows 7 and 16GM of RAM.
I had this theory before that is would happen when my units were attacking uphill with the enemy concealed behind fences and stonewalls, but never fully researched it.
Is there anything in the mod that affects the way units interact with stonewalls or fences difference from standard ETW?
