Journal entry 20 for quest TR_m1_Bah_widow updates upon activating the skeleton at Urlis Rock even when the related quest has not been started. If the PC has not started the quest, there should be either a distinct journal entry with a different quest hook or no journal entry at all when activating the skeleton.

Also, the wording of the existing journal entry is a bit rough.

I have found Gavis Arantam, but it is clear that he has not drowned. A blade was thrust through his heart. I should probably investigate this. I could start by asking whoever was with him that day. Lliretha Arantam said that he had been fishing with Vedran Gavonir.

Changing it to something like this would probably be better:

I found the skeleton of Gavis Arantam, but it is clear that he did not drown. A blade was thrust through his heart. Lliretha Arantam told me that he had been fishing with Vedran Gavonir; he may know something about what happened.

And this could be the entry if the quest was not previously started:

I found a skeleton on the seafloor near Urlis Rock, with a blade thrust through its chest.
