Wizard frogs in LGuk are casting through walls. Yes, they're beginning casts IN LOS and finishing them OUT OF LOS. But they are also beginning casts OUT OF LOS and finishing them OUT OF LOS. This basically means that a wizard mob, once attacked, has free reign to cast on his attacker without regard to walls. This has been going on ever since the most recent patch which modified spells cast during LOS to be finished out of LOS; in LGuk at least it is clearly not just limited to that condition.

It's not just limited to targeted AOE spells; single target nukes and roots are being cast without any regard to LOS limitations. As you might imagine, this makes pulling casters in LGuk vastly more difficult than it should be.
