Slow-Motion Units Since Patch 3

[Quickening]

Since I've been playing Rome 2 after patch 3, there are rare cases where my units will move in slow motion in battles. This makes the battles extremely gruelling. I just had a battle that lasted for forty-five minutes while I sat there reading. Has anyone else experienced this? Is this a known issue?

on Ponuts campaign I had a single enemy cataphract (last of his unit) got stuck between some small buildings outside the settlement and the framrate went to diashow and the battle never ended...took me a while until I realized what was going on...I sent some missile troops (cause he couldnt be attacked in melee) and the moment they killed him the framrate went back to normal...
there may be an issue with collision under certain circumstances...
