Streetcomplete: undo does not allow to reanswer quest

[codingcatgirl]

If i answer a quest incorrectly and undo it, the quest does not allow me to reanswer it correctly. But most times when i know that i answered it wrong, i also know the correct answer and want to give the correct answer. however, after undoing my last answer, the quest dies not appear again.

This behaviour is present for me in version 3.6. I don't know whether this is a bug or intended, but i would wish very much that it was possible anyway. This is propably related to and possibly even a duplicate of #681, but that issue is closed and sounds like it was resolved. Still, undone quests do not reappear on the map for me.

Do you have this problem with cycleway or housenumber quests?

Because for certain quest types, this feature is disabled. Namely, for cycleway and housenumber quests, otherwise it should work. This is a technical limitation as some quests are too complex for the app to determine if they should be shown now or not without making another overpass query (= downloading the area anew). So this would be a will-not-fix.

Also, if I remember correctly, if you turn off the auto-sync in the options and always manually upload your changes, then, not-yet-uploaded changes that you undo will always reappear on the map, as the underlying mechanism is different. (It is just a local undo, not revert of the committed change)

No, i had that issue it with number of hose levels, speed limit, and opening times. I never undid something and had the quest reappear again. Not even after clearing the cache :/

[codingcatgirl]

I now disabled auto-sync and will see if the issue persists even there. But if i understand you correctly, it should not happen with auto-sync either way :)

Okay, can reproduce

[westnordost]

Oh damn, this is a critical bug. It also exists since v3.3

[westnordost]

😓

[codingcatgirl]

Whoah, that was unexpected! all my smpathies to you, this is certainly the kind of bug you never want to have ^^

it would be soo nice if there at least was a way to find out which edits i tried to revert… but skimming the source code it doesnt seem to be possible… but if it was possible you propably would have noted that anyway.

Nevertheless: Thanks for your work!

Yeah, changes that failed to apply due to conflicts are dropped from the database, so no trace is left.
