when it comes out for console will it fix whindhelm house glitch where chest wont appear and dagger case eats daggers will it fix them or is my mahrunes dagger forever lost LOL.

if you already lost the dagger its lost it aint comming back :/

If the rack threw the Dagger into the Void, it is gone and no patch will bring it back. New saves going forward should not have the problems.

Yeah, no bringing it back, sorry to say.
