Does line of effect negate unlimited range spells?

[kinderschlager]

Main examples are sending and nightmare. does the range:unlimited of the spells actually exist? a single door or rock in the way and the spells fails. Is this a case of paizo not clarifying or exempting unlimited ranges from normal line of effect rules?

Strictly RAW, you still need LoE and LoS for them.

RAI, it's a screwup and they should work without LoE or LoS.
