slophlong: And you tried asking Mavrick to come to the beach with you? Once you get there you should have a few options, one of which leads to the quest being completed.
therpgstore: oh that i didn't try i thought if i came with him to the beach he would get killed as the specter said , ty for the info :)
Yeah it's not bugged or a bad quest. All it took was common sense. How would you negotiate between two parties to discover the truth? Bring them together obviously. Asking someone directly as the option has with Maverick would obviously lead to denial and run off. Put him into a position where he can't run away.
Plus if you read the Journal with quest entry it gives you massive hints so you don't even need Maverick or tell the Spectre you will investigate further. You know from asking around and from Dethmold the father had something to do with demons. If you spent time in the graveyard you'd realize there are only 2 sisters and a brother and the specture is lying.
Anyway, I digress, as others said. Threads like this are stupid when players are blaming the tool when they are the fool who didn't use common sense.
