Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Got a softlock (white screen, infinite loading animation in the corner [that circle]) right after Saki starts praying outside the battle on the beggining of the game on pretty much default settings (PPU LLVM + SPU ASMJIT + Vulcan, no additional things, no WCB). No graphical problems, no sound problems, FPS's through the roof all the way from clicking "Start" until that moment. Went through after setting up 60FPS limit. World Map works without any single problem. Only synthesis goes critical.

Using PPU Interpreter and\or WCB makes game go sloooow and makes some textures go rainbows.
