Create a closed way `A` with more than 20 nodes 2. Create another closed way `B` with exactly or less than 20 nodes 3. Multiselect closed way `A` and one of its nodes `A1` 4. Hold the left mouse button and Ctrl key to enter merge mode 5. Drag the selection near closed way `B` such that the cursor is directly above one of its nodes `B1` and changes icon to indicate intent of merging 6. Release the left mouse button 7. Observe the resultant action 8. Repeat steps 3. to 7. with closed ways `A` and `B` swapped ==== What is the expected result? The selected node `A1` from closed way `A` should merge into the node `B1` from closed way `B` directly below the cursor and the rest of the nodes from the selection should be offset by the same distance to retain the original shape of the closed way `A`. It would appear as if the selected closed way `A` 'snapped' to closed way `B` via their respective nodes `A1` and `B1`. The same result should be observed when merging the selection of the closed way `B` and one of its nodes `B1` to one of the nodes `A1` from the closed way `A`. ==== What happens instead? In case of the selection of closed way `A` and one of its nodes `A1`, `A1` does not merge into the node `B1` when the left mouse button is released. Instead the selection places itself at the last position it was in during dragging mode. In case of the selection of closed way `B` and one of its nodes `B1`, `B1` successfully merges into the node `A1` and offsets the rest of the nodes from the selection by the same distance as intended. ==== Please provide any additional information below. Attach a screenshot if possible. This defect was discovered while using the merge feature for 'snapping' buildings i.e. to align buildings along a common way or connect adjacent buildings together when it failed to connect buildings with complex geometries with each other. This feature could prove extremely beneficial to modelling symmetrical and perfectly aligned buildings once this defect is addressed. {{{ Revision:19555 Is-Local-Build:true Build-Date:2026-06-29 19:38:35 Identification: JOSM/1.5 (19555 SVN en) Linux CachyOS Memory Usage: 792 MB / 11800 MB (272 MB allocated, but free) Java version: 26.0.1, Arch Linux, OpenJDK 64-Bit Server VM Look and Feel: com.sun.java.swing.plaf.gtk.GTKLookAndFeel Screen: :0.0 1920x1080x[Multi depth]@144Hz (scaling 1.00×1.00) Maximum Screen Size: 1920×1080 Best cursor sizes: 16×16→16×16, 32×32→32×32 Environment variable LANG: en_IN System property file.encoding: UTF-8 System property sun.jnu.encoding: UTF-8 Locale info: en_IN Numbers with default locale: 1234567890 -> 1234567890 Desktop environment: KDE VM arguments: [--add-modules=java.scripting,java.sql, -Djosm.restart=true, -Djava.net.useSystemProxies=true, -XX:MaxRAMPercentage=75.0, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED] Dataset consistency test: No problems found Plugins: + FastDraw (36474) + PicLayer (273) + ShapeTools (75) + apache-commons (36474) + buildings_tools (36474) + ejml (36474) + imagery_offset_db (36474) + log4j (36474) + reverter (36474) + terracer (36484) + uberterracer (1718732356) + urbaneye3d (2.4.2) + utilsplugin2 (36497) Tagging presets: + https://cdn.jsdelivr.net/npm/name-suggestion-index@latest/dist/presets/nsi-josm-presets.min.xml + https://josm.openstreetmap.de/josmfile?page=Presets/Simple_Indoor_Tagging&zip=1 Map paint styles: + /plugins/indoorhelper/resources/sit.mapcss - https://raw.githubusercontent.com/yopaseopor/indoormap/master/indoormap-style.mapcss - https://josm.openstreetmap.de/josmfile?page=Styles/iD&zip=1 Last errors/warnings: - 00028.373 E: Failed to locate image 'reset_camera' - 00028.374 E: Failed to locate image 'satellite' }}} " defect new normal Core template_report
