I was making a quest for Quentin and i got the error of host(the one image of cloudfare or something like that?). Now get the "Oh No! You aren't on a quest!" when i try to complete it. I buyed the items 2 times and now i cant... What i do?..I will cancel the quest... but is a weird error...

If you get the "Oh No! You aren't on a quest!, it should mean that when the 502 page loaded that actually you had completed the quest. You should have the quest reward in your inventory.

What do you mean "I buyed the items 2 times and now i cant..."? What cant you do? Are the two items still in your inventory or are they gone? If they are gone then the quest was completed, and you can go do a new one :)

i wasnt able to finish it, when i click "finish quest" i saw the monster of the error appear, i saw the items gone, but i cant move from that part. I end click on quit quest, but is so strange, for my luck was on the lap 9/10 quest, so i only lose 1 quest. No idea what or why, but i dont know if i get a reward for the quest or not (i see the host thing error and i wasnt able to know the complete or not, but i guess is not completed and takes the quest items too).

But you are able to do quests fine now right? :) In that case it isn't a bug, it's just one broken page that messed you up a bit.

In the future, just go back to the quest page if you come across a broken page when trying to start/complete a quest. https://subeta.net/quests.php/quentin The above page will show exactly where in the quest you are at, whether the broken page took your items (it will show as you are able to start a new page) or if it is still asking for items, you can try to complete the quest again :)

Not either of below links, because it can be confusing if you had a broken page: https://subeta.net/quests.php/quentin/finish https://subeta.net/quests.php/quentin/start

Hope that's clear?

Yeah but is not fair if the system quest takes the item and dont leave me complete it, i lost this time 50.900k but imagine if this happend at sagitarius quest i will broken of money. I cross fingers of that dont happend again, i got lucky for the quest npc wasnt too much expensive. I dont remember the name of host when the error appear but is a trolling troll in full rules. Anyway thanks, i just hope this dont happend me again and less with sagitarius quests.

If the quests took your items, they should have rewarded you. Did you check your inventory/on hand sP for a different count?

If you really want you can also try to file a ticket and see if they can find what you received for you :)
