The new rate limiting prevents participants to Missing Maps mapathons from saving buildings

But note that using the JOSM validation function, it did not report these non-orthogonal buildings The Changeset session144564707mapped three days ago shows such quality mapping problems. Have the JOSM rules been modified and not catching overlaps and non-orthogonal buildings anymore ? Or do I need to specific parameters in JOSM ? JOSM Preferences - Data validator panel - all options are already checked.

With Changeset: 144564707 | OpenStreetMap I get warnings about overlapping buildings. I do not get any for Changeset: 144106801 | OpenStreetMap. Building with an almost square angle seems to need a download area (bug?) and is only an informational (other) warning and , yes, the minimal and the maximal angles are configurable in advanced preferences (validator.RightAngleBuilding),

BTW, clicking on building and pressing “O” doesn’t work in my JOSM (it will complain about Please select exactly two or three nodes...). And even if it worked, circular building would be at wrong place and in wrong size, which is not much (if any) improvement.

So deleting and recreating is faster and less effort (click for details)

In order to fix it correctly, easiest way in JOSM using O for correctly converting “fake” square building to correct circular one is (as far as I know):

• click on one node of original square building
• press delete
• click on second node
• press delete
• click on third node
• drag and drop it on one part of the circle
• click on fourth node
• drag and drop it on second part of the circle
• press ‘O’

compare that with default JOSM remove-and-readd:

• select building(s) (click or drag bbox for multiple) (only once)
• press delete (only once)
• press ‘a’ (only once)
• click on one part of the circle
• click on second part of the circle
• press ‘O’

or even shorter (with building_tools):

• select building(s) (click or drag bbox for multiple) (only once)
• press delete (only once)
• press ‘alt-z’ for building_tools circular mode (only once)
• press ‘b’ (only once)
• click on one part of the circle and drag to another

(which is significantly less work, and that work is easier and less error prone due to less mouse movements – especially as first two bullets can be consolidated by drag-a-square-and-delete-multiple-buildings if there is more then one wrong building)

But that is getting off-topic: I was just trying to note why many users do delete-and-recreate instead of modifying existing objects, and so why such behaviour should be taken into account for vandalism countermeasures as it IMHO isn’t going away.

The shortcut O works for me but it does not add any nodes, i.e. rather useless with a way with less than five nodes.
As already mentioned, please, use “Replace geometry” from utilsplugin2 if you want to replace a geometry. Simply draw a new, accurate way, select the new way and the old one to replace and press Ctrl+Shift+G.
