Spellcasting range while on a hill is borked.
 

I've noticed an issue with spell range the last few levels while quad kiting on my 31 wizard. If I am on a sharp hill or elevated above the mobs I am kiting (my guess would be 40-50 in-game units of elevation, without actually having taken a measurement), then effective spell range is cut down to almost nothing.

I can spam debuff with my Staff of Temperate Flux, because clearly the mobs are in range, but I recieve OOR messages on all casted spells right up until the mobs are almost in melee range.

This bug is easy to replicate, just stand on a hill over a mob that is cearly in spell range and attempt to cast.

It's not a game-breaking issue, but it is annoying to work around kiting anywhere that has sharp hills (OT perimeter, WW near dalnir, etc).

Edit: Upon further investigation, it seems only targeted AoE spells are affected. Single target spells show no decrease in range. Perhaps this is some obscure classic idea I've never noticed?

Target AE may be using x y and z for range. Pretty sure i matched single target behavior on server to what client does. The other could need adjusting.

How are the casting doing nothing, on hills looking? Tried some fixes for that.

I've only had two or three casts out of several hundred doing nothing while on a hill - its uncommon enough that I cannot replicate it.

More commonly, I just get oor message spam until I move the mobs to more level ground. I'll try some different AoEs tonight - right now I've only cast Column of Lightning.

Also noticed I couldn't cast on mobs in KC while standing above them on rampart - used to be able to do this, couple other weird Z axis bugs since patch.
