Over the weekend was helping someone with there lvl 60 twink. Luckily he took my advice to get certain things out of the way at level 58 or this would have been a twink killer... One of those things being the SL Ring quests.
In doing the +2 ring quest he was set to 100% global research, had the no xp gain checked and was teamed with my 195 doc. Upon completing the quest ergo was nice enough to level him from mid 58 to mid 59. Reported and ARK/GM verified the xp gain/level and said they will look into it and report as a bug. We intended to move right to the +3 quest, but now are looking for confirmation from someone that they were able to do the quest without XP gain, otherwise I guess that might be it for the rings for that twink...
Anyway, heads up if you are building a twink and want to do this quest or any other for that matter... and again, if you have completed +3 ring quest without XP gain I would love to hear from you.
