JUST so you know how it works at moment. Player reports a quest not working, ether petition or tells, Petition is best.
1. Reply to Petition or tells, find out were it is going wrong.
2. Gm then tests quest.
3. Get to point of reported problem, try all ways to solve problem.
4. IF same as player you are stuck at this point, report to Dev.
5. Dev looks at problem, in most cases it can be fixed shortly, [hummer note not soon[tm] ]
6. Fix is implemented, will take effect from next server reboot or crash.
Are you really wanting all quests wiped, and have to do all over again ? get me this get me that do this do that run hear run there, having completed over 80 on my player, I do not want to do them all again, because I am having problems with one.
