House of Sorrows Glitch *Minor Spoilers*

[Onion_Duck]

So I started the House of Sorrows questline, went through the proving halls and got inside the House of Sorrows itself, before talking to the questgiver I exited the house to finish exploring Klurikon. Now I cannot re-enter the House of Sorrows via the front door or the proving halls, the Heartstone (Which apparently is the key to get in) has long since been sold and cannot be bought back. As far as I know there is no fix for this but if anyone knows one it'd be greatly appreciated. Thanks.

they say to not sell or destroy it cause you need it to get back in. unless you have a save where you still have it.
other than that ???
sorry.
