My enchanter hit 125 last night, and an odd issue started happening with the auras. I have the chanter set to use the combat innate aura & twincast. First, they will cast them both properly. After both auras up they seem to get instantly removed, the chanter then sits back down and recasts both auras. It goes on in an infinite loop like this until I change the combat innate aura to something else. For example, if I use Mana Aura & Twincast instead, the chanter will get them both up and they stay up as expected. I noticed this first happen in Laurions Inn when I mem'd the 125 spells, but it also happens in other zones as well.
After playing around with it a bit, I discovered that this only seems to happen when I have Aura1 set to combat innate and Aura2 set to twincast. If I flip that selection, so Aura1 is Twincast and Aura2 is Combat Innate then twincast aura will stay up but the chanter will cast the combat innate aura, it will go away after a few seconds, and then the chanter will recast it in a loop.
This was not happening with the 120 version of the combat innate aura. Let me know if there's any other details I can help provide.
