What do I do? "Mai's Training" and "I'm bored" cannot be dropped, and I have no way of completing Mai's training. Can a gm force-remove this quest from my list?
Simply as Matt stated above. Those two quest do not affect the no drops/spawn glitch. I have both of those quest active on my non GM character, which I cannot forfeit either one of them. I have never received the no drops/spawn glitch on my legit character training from level 10 to level 70.
There's most definitely some correlation between Mai's Training and the glitch. More than half my encounters with people as of late have been in The Field East of Amherst, involving them being unable to gain any credit toward the completion of this quest. This is often swiftly followed by the spawn The Field East of Amherst, The Field West of Amherst, A Split Road and The Field West of Southperry—the maps one must pass through in order to reach Southperry from Mai—being out of order. Yesterweek (before the weekend server crash) I also engaged in a brief experiment on the matter; upon creating three temporary characters and accepting Mai's Training I was able to consistently break my own ability to gain drops. My anecdotal evidence further suggests that the above maps in order by frequency of breaking is as follows: The Field East of Amherst The Field West of Amherst The Field West of Southperry A Split Road Given this I hypothesise that for a map to break when one has a glitched quest, one is required to attack (and possibly kill) a monster in this map: almost all players with Mai's Training glitched will attack monsters in the first one—where Mai is. A few might attack monsters in number two. Most people simply jump down to the portal in A Split Road and therefore never interact with enemies at all, hence it very rarely breaking, and the third map above would encompass roughly the same people as the second one.
Very possibly. It tends to break at Mai's First Training, the one with stumps, which in turn is a quest following Stan's quest. Edit: it is perhaps worth noting that Chief's Introduction, which initiates Mai's Training, is special in that it specifically requires a host of other quests finished in order to be completed. Whether this is a common trait on the continents I do not know, but it might be an interesting common denominator to look out for.
