well as i think to make an tvt npc u just need an L2Npc in the event creation if u set max level to 80 u just made ur first error u have to set it to 81 dont ask why but if u do that the event works, i always use the event manager if u want to know the id just do //spawn event_manager i have never seen that npc in any place so i always use that npc, and for the engine idk if it works, i have it but my folder dont have /cron
