[GAMEPLAY] Mordekaiser 2nd W does not damage all targets in range

Sometimes, the 2nd cast of Mordekaiser W does not damage all enemies in the ring around him.

Sadly, I do not have consistent repro steps, since the bug only happen sometimes, but it happens often enough that you should be able to at least confirm it relatively easily, if not squash it ^^'

A few stray observations that could help:

• Only seems to happen with Minions, not Champions (hopefully, that would be game breaking otherwise).
• Doesn't seem to happen when you "take your time". Using E from the front of a minion wave, then positioning properly in the middle of it so that W hit them all seems to work consistently. On the other hand, when you have to chain abilities together to last hit under tower, the bug seems to happen more regularly.
• Maybe an issue with the targets inside the ring not updating properly/fast enough?

I'd appreciate any feedback/confirmation ;)
