How did Trevenant avoid the move Scald in this battle?

Question

Suicune is fast asleep.
Suicune used Sleep Talk!
Suicune used Scald!
The opposing Dekubaba (Trevenant) avoided the attack!

Scald has 100% accuracy and I thought that 100% accuracy moves cannot miss... also my Suicune didn't have an accuracy drop and Trevenant didn't have an evasion boost.

---

Am I missing something or can 100% accuracy moves miss? Or was it a glitch?

Copy pasted from your battle log.
Phantom Force, like a few other moves, gives a turn of semi-invulnerability. There was no glitch, there was nothing wrong - you just failed to realise that he had used Phantom Force.

There is another way it could happen though not here .  two hold items, lax incense and bright powder lower opponents accuracy by ten percent , any move that doesn't avoid accuracy moderators can miss
