Assassin extended True Strike

[yune]

Trying to cast extended True Strike as an assassin via quickslots or right click menu actually casts a non-extended one from a level 1 slot. If you have no non-metamagic ones left or didn't prepare any, it says no uses or preparations left for that spell even if you have many extended ones prepared. Other non-swift action spells like caustic weapon work as expected when extended.

Also, might be intended, but casting true strike clears your action queue unlike other swift actions like disarm.

For Assassins, when extended True Strike spell is cast, it uses a level one slotted True Strike Spell. In effect you need to have one Extended True Strike spell at 2nd, then use your 1st level spell slots for True Strike spells.

Does doing that give double duration?
