After a multi-year game break just returned to DDO a couple weeks ago. Did Enhancements on a couple characters, than ran one through several Gianthold runs on Epic Hard. Decided to modify my character some to better match current gameplay, and used an old LR+5 heard I had in the bank as I was swapping a couple of levels along with some stat/skill tweaks.
First off thing I noticed was my favor was reset. Annoying but could live with that. Doing a /quest completions shows old raid totals, even though my quest list is nearly blank. Didn't notice that part until after a couple more GHold runs as I was trying to complete the Saga for reward.
What really makes it clear I'm bugged though is that 3 reward givers in Gianthold showed the green checks over their heads still after Saga completion. Clicking on any of them gave the same result: first they'd offer me min level 1-3 items, totally under-leveled for Epic Hard completions. And taking the items, the check was still over their head. I could (and did) keep taking these under-leveled items until hitting reward ransack. Oddly, as I walk around public areas, every few minutes I get the quest completion popup/notice at the top of the screen too. (Haven't timed it to see if it's random or every X minutes.)
Guild members pointed me to this video (http://www.youtube.com/watch?v=Ky4S4ymXDLY) showing someone who similarly can take rewards and the givers still show the checks after giving the reward.
I really haven't completed any quests since as I don't know if each quest completed now will be bugged or not. I went to Meridia and I was able to enter the Shroud raid, but I stepped in solo just to see if it would let me in so I don't know yet about finishing/timers/repeatability.
But it seems this may be a known bug? I was told by a guild member the only "fix" might be a TR, but I don't find acceptable and would like an official Support response. So please advise. Character is Gimmel, on Thelanis.
PS I have a couple more banked BTA LR+5 hearts from ~3 years ago that were store-purchased. Would like to know if they're "safe" to use as I have some other characters that need minor adjustments and if possible I'd save the free LR20 hearts for later in case a more major overhaul is desired. I did use one of them on another character of mine and that went fine, but waiting on all further LRs until I know how likely it is that other characters could get bugged with either type of LR heart.
