Game Mechanics: Z axis playing a huge partin AoE spells (maybe just spells?)

[Ashintar]

While quadding giants in Eastern Wastes today I noticed that the Z axis placement is playing a huge role in the distance check.

I rooted a giant and levitated up high above it, casting Pillar of Flame and taking /loc checks here is the output. I wasn't high enough to play a quadding wizard when Velious came out the first time, but this distance check seems out of whack?

Works the same on live p99. Quadding yetis in DL or specs in oasis requires a lot of z positioning.

[Rogean]

This is mechanics not spells, and is not specific to velious.

Moving to global bugs.
