Aliens "Ghosting" through walls?

[Chris]

So it's been reported in many instances that aliens are just walking up to walls and "ghosting" through them.

From what I understand, this only occurs with cover walls like fences that don't block line of sight, rather than solid structural walls. I'm therefore pretty sure that the problem is missing vault animations - if the alien does not have one set, it will just play the idle animation when a vault occurs and this looks like the aliens are phasing through solid objects.

Can you guys let me know what mission type and alien races you've seen doing this, please? I need to have a look at the issue and see if it's something that is a case of mis-set sprites and missing animations, or it's a pathfinding bug that's telling units to vault things when it should not be possible.

I've only seen this with Androns, and yes, they were all with half-walls that my own characters (except shield wielders and Predator wearers) can vault over.

yep, ive only seen this with androns on half walls as well.

I've only seen Androns walking through half-height walls but I just assumed that they walked through them because they just didn't give a fuck.

I and someone else reported that they ghost through solid walls and can get stuck on the object that is behind it, allowing player to shoot the alien and the alien can't do anything.

I think I've posted it here - but strangely this one gets database error.
