So far for us, we"ve seen the Bertoxxulus event spawn a few times, usually in the middle of the night, say 12am-1am PST. It then despawns within a few hours. Nothing in particular seems to trigger it. We"ve seen it spawn 18 hours after server up with Carigin still up. We"ve seen it spawn 6 hours after High Priest killed. I petitioned this and a QA GM told me he was bugging it. Has anyone seen this encounter up in a usable form at a reasonable time?
