Shield Charge + Mirage maps

In a map with the Mirage enchantment, using shield charge will result in EXTREME rubber banding due to some weird interaction where the game knows that there are monsters in the mirage/map but your character is in the opposite area. That's the best help I can give you in finding it, you guys are very smart I'm sure that will suffice.

You can replicate this yourself by using shield charge in a mirage enchanted map and then going to blood aqueduct and shield charging. In the mirage map you will be rubber banded ad infinitum while in BA you can charge to the edge of your screen with glee.

Cheers
