Hello,I have a problem with the double bed in the main hall of Lakeview manor that i couldn't find anywhere else on the internet...The two children beds work fine,but the green double bed just shows me (like it should) "press e to sleep!" but nothing happens! Moreover,my spouse will not use it! Has anyone ever experienced a similar bug?

maybe you should wait a couple of days outside Lakeview manor that the house 'resets' after an absence from it

Or maybe you should try to respawn your bed if possible...

How do I respawn it? using a console command? waiting doesnt do anything unfortunately

Re-boot your PC and load from savegame.

Typically the former can be even more beneficial than the latter...

It's Skyrim, right?
