Now whether the arcane magic was messing with the magical guidance systems I don't know but look at the two screen shots to see how it wouldn't let me target past the magic wall!
It was no big deal...even though I couldn't flatten that witch psionic girl...ahem...but I thought you'd want to know Ross.
I also attach the log report in case it reveals anything.
Magical walls block line of sight just like physical walls ;)
seeker missile is 8 countable tiles, so with LoS you have to actually trace around the wall to see if they are in range. But the wall placed right there, blocks said LoS, so you must count around that, and 8 spaces is not enough to do that,
Oh I see - I thought it was a radius of eight squares I didn't realise it counted that from a LOS point of view - my mistake.
I assumed because you could fire it over walls that it ignored them.
