Elusive Carcosa - If two events are on ringworld (Ringworld start), both can comlete, but counter gets only one

Massive Modded Game, started on decayed ringworld. Colonized some worlds and also both available segments, event triggers, one location of carcosa hunt is on a planet, two are on the colonized ringworld segments. All sites completed, but Planets searched shows 2/3. Is now stalled for decades. Anyway to increase counter to proceed?
