After Patch today (19.04.2018) Raid quest still not working, but they fixed the reset position bug at LC, great job finxing unimportant things before gamebreaking things o/
Edit: After relogging and reaccepting the quest several times it seems to work, i had to run 5 times tho
1st char => 1 time per quest, everything worked fine tho
And don't you consider a glitch that clears a raid that fast something gamebreaking?
gamebreaking is for me sth that doesnt let you get progress in any kind e.g. not being able to clear a quest
