Crystalshaper quest deleted my ARoP

[Darkwing_Duck]

luckily I only just started it, so I didn`t get far, but right when I started the crystalshaper school quest, my ARoP quest got deleted. Is this a common issue? or a bug? Should I wait to start ARoP until after I`ve finished the Crystalshaper quests?
I`m afraid if i get far in ARoP, it might get deleted again and I`ll have to start all over.
Anyone else having problems with quests canceling out other quests?

You won't have to start over. I believe it was redone so that you can re-acquire the quest at any time, and it will be on the part you were on when you dropped it.

As for having to do the quest over - my alt had his part with the Rift Guardians messed up. I dropped and re-acquired the quest a couple times and didn't have to do anything over except go talk to a NPC.

I started the crystalshaper stuff the day it came out, while being near the end of my ARoP (Rift or quest just before Rift) and had no issues like you are describing. So there isn't any need to worry that I can see.
