So I was going out to vanquish Gyala Hatchery (explorable ) right and I get right out into the zone and pop my celestial summoning stone. After killing the first group i noticed I didnt have any stars following me. I knew it hadn't died and i knew i had popped it cuz i had the sickness. Turns out if you use a summoning stone right outside Laviathan pits it gets stuck in the stupid giant ass mechanical crab above you. So i tabbed out to basically type this out and when i got back in game like 5 minutes later the celestial dragon was gone.

Rofl, that's actually pretty cool. Did you try it any other times to see if it happened again or was it a one time occurance? I'm also wondering if it was because you got the dragon and it flies, although I have no idea why it would be that high up.

Shoulda popped a powerstone of courage. Or 3.

He didn't have his Scroll Of Reckoning.

i think the area is poo for summoning stone creatures period. if they dont get caught up above they do some other stupid useless thing. -shrug- like rubberband far away like the aggromaster or something. .. bleh.
