Actually finally find him after hundreds attempts.
The game's save slot 1 is broken in my situation, so wes won't spawn at all if I keep trying using slot1
I alway get Archipelago > A Cold Reception > Two worlds (9 out of 10 times)
the other time I got A Cold Reception > Game is Afoot > Archipelago
Seems if you get a world with
worm holes as third world you won't find Wes.
After checking up ps3trophies.org forums today, sb says if you stuck with two worlds as third world in game save 1, you can try use save slot 2 to find him.
Tried this method. it really worked, although I almost give up, since he located at the far end of the whole map, even after the wood platform that you use to assemble 4 pieces. Cursing this Freaking Wes.
Gonna post a vids on youtube soon, will update this post afterwards.
This game's adventure mode is so broken I have to say. Super irritated
