To progress the TR_m3_TT_RIP quest after delivering ashes to Necrom, a player needs to talk to TR_m3_Garvs Ovav about the topic sacred task to progress the quest. This is misleading and unintuitive, as the ashes are Fedura's, and that is the topic that the player uses up until that point to interface with Garvs regarding the quest. sacred task comes out of nowhere for this particular NPC.
Fix: move the relevant content from the sacred task topic to the Fedura topic. The Fedura topic is already prominently featured in his relevant Greetings, so this will make this stage of the questline considerably more intuitive.
