I completed the Rubricator excavation, but the event spawning Shard would not fire after ancrel.4017. I noticed that the code in your ancient_relics_arcsite_events_1 did not match the one in the game folder, so I tried copy-pasting the Rubricator-related events from the game folder onto ancient_relics_arcsite_events_1, reloaded a save before finishing the excavation, and then everything worked perfectly.
