I don't see this listed in the claim browser, so I think it is best to report it so it will not be forgotten. Bel-Betu's second quest, "Expedition to Barzamthuand" (TR_m4_wil_BelBetu2) has journal entries, but is not implemented. In his dialogue, he explains that he needs special scrap metal from Barzamthuand (topic "scrap metal"; this topic also needs additional filtering, so it cannot be read before finishing the first quest). The metal exists, but there is nothing triggering the journal entries.
