Casterly Rock Siege Bug

[Ashba]

Alright, first of all, lovely mod, models look amazing, i'll try to donate as soon as i can, keep it up guys!

Now to the bug report:

it's happened twice already, different save files. First i was a Lannister Vassal defending Casterly Rock from the Iron Islands (yeah somehow we were at war) and the entire garrison + my army was running towards a wall next to the castle hall entrance, funny thing is, the enemy was doing the same at the other side of the wall, i ended up leaving the battle, after all, it's Tywin's castle not mine.

Next i was playing as a northern, attacking the castle and all of my men were doing okay till they got to the walls surrounding the main hall (the lannister army spawn point). Same thing happened again. it doesn't matter if i command them to follow me, they won't, and i can't finish the siege by myself, i tried and the crossbow guys absolutely destroyed me. They keep spawning there while my men do nothing, i had to retreat from battle because no one was doing a single thing. Also, i had to use the good old "order your men to attack while you stay back" till they were down to 30 men. BUT then again! one crossbow guy was stuck in one of those weird corridors next to the training ground and no one couldn't reach him! I was forced to use Alt+F4 with that last guy.

It's the only annoying siege bug i've found, the other one is smaller and doesn't require retreating/cheating, which is in King's landing, some guys get stuck next to the 'bridge' that's close to the red keep/throne room.

Please take a look at those bugs guys!

EDIT: i just copied my current save into a new slot in order to mess around and take pictures of this bug
