Describe the bug
When completing a task, you select whether to get a random task, or the next closest task. Nearby no longer selects a close task at all.

Expected behavior
Nearby selects the next closest task.

To Reproduce
Steps to reproduce the behavior:

1. A good example is this task: https://maproulette.org/challenge/43001
2. Pick a task in let's say Wisconsin and complete it.
3. Complete the task and request the next task to be Nearest. The map will show that there's definitely a close task to jump to.
4. It jumps to a random task instead of a close task.

Desktop (please complete the following information):

• OS: Windows 10
• Browser: Vivaldi 7.1.3570.50, which is a Chromium fork

I just tried:

1. Select task https://maproulette.org/challenge/43001/task/274014757 and fix it (way https://www.openstreetmap.org/way/467553926#map=19/42.240380/-83.616128) - Ypsilanti MI
2. Select Nearby for next task
3. Next task presented to me is https://maproulette.org/challenge/43001/task/274010319 which is way https://www.openstreetmap.org/way/1351884708#map=18/38.921433/-76.998598 (Washington, DC)

Looks like there are however plenty of nearby tasks that could have been selected:

So this needs to be looked into, thanks for reporting

More investigation:

If I manually select a task initially, I can reproduce the error.. to an extent.

1. Select initial task manually from the challenge browse page
2. Skip
3. Next task will not be nearby

If I click start on the Challenge browse page to start with a random task, the next task will be in the same area.

@mneko are you seeing the same?

@mvexel I'm not sure how my setup differs from yours, but hitting Start instead of preselecting seems to have the same issue.
Start sent me to Tempe, AZ, then Nearby picked Los Angeles when I'm certain there's plenty left in Arizona.

Interesting, but probably a separate bug: Start also immediately sent me to a Skipped task when as far as I can tell, the algorithm is supposed to prefer untouched tasks first.

I'm guessing it has something to do with the prioritization of tasks (you have some low and high "priority" tasks)... Hard to say and I will need to investigate this more, but it's been an issue in the past so maybe it's still an issue.
