so i was playing as the iceni and when i use my chariots they all die from tripping over each other or a rock. my general keeps dying is there anyway to fix this or does anyone know where the value for that is so i could fix it? i looked through pfm and havnt found it yet

EDIT: Tried as egypt and still killing them selfs also tried to see what was killing them and it seems when they collide with other horse units or them selfs(as in there own unit or another friendly chariot unit) they will die but charge them into friendly pike men and nothing happens so it is 100% to do with the horses also tried charging horses into non moving chariots and it didnt kill them only when the chariots are moving does it kill them i just downloaded the assembly kit and am trying to see what it can do about the problem (never used the kit before so i dont expect much)
