No you didn't get it. If it just you zone out or go ld it's np, he's talking about whole group going to anotjher place and maybe even breaking up and geting back to the saved persistent instance. We had same problem just today. Cleared first bone tower and picked up items that you need to spawn Terror, then we even spawned Angst but it was already raid time so we went to raid. When we got back after raid no skull was up in the bone tower we cleared so we couldn't spawn last mob and even Angst despawned and we couldn't spawn it back. So as you can see SoF isn't really a persistent zone which is sad

We couldn't even get a GM to help us cause they seem to be not at work atm as MoTD says. Waited 2 hours and nothing, no response on a petition. ehh
