Update system then launch JOSM + Bing imagery 2. Press and create house; press - and split in two (semi-detached) 3. Whilst semi is selected; press and create 'house' for rear extension of semi; press - and also split extension in two and line up with front houses 4. Select front & rear of semi-detached, then press - to join front + back of semi-detached ==== What is the expected result? Full outline of semi-detached house ==== What happens instead? Overlap gets made into a multipolygon instead ==== Please provide any additional information below. Attach a screenshot if possible. I'm not sure exactly when the behaviour changed. However, JOSM-stable (11639) is fine, and I've attached screen-shots of the create process through to completion to try to help understanding. {{{ URL:http://josm.openstreetmap.de/svn/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2017-03-19 02:26:34 +0100 (Sun, 19 Mar 2017) Build-Date:2017-03-19 02:34:23 Revision:11746 Relative:URL: ^/trunk Identification: JOSM/1.5 (11746 en_GB) Linux Debian GNU/Linux 8.7 (jessie) Memory Usage: 687 MB / 1636 MB (149 MB allocated, but free) Java version: 1.8.0_121-8u121-b13-1~bpo8+1-b13, Oracle Corporation, OpenJDK 64-Bit Server VM Screen: :0.0 1366x768 Maximum Screen Size: 1366x768 Java package: openjdk-8-jre:amd64-8u121-b13-1~bpo8+1 Java ATK Wrapper package: libatk-wrapper-java:all-0.30.5-1 VM arguments: [-Djosm.restart=true, -Djosm.dir.name=JOSM-latest, -Djava.net.useSystemProxies=true] Dataset consistency test: No problems found Plugins: + DirectUpload (33182) + Mapillary (v1.4.2) + apache-commons (32994) + apache-http (32699) + buildings_tools (33004) + continuosDownload (53) + terracer (33088) Last errors/warnings: - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet - W: java.io.IOException: Attribution is not loaded yet }}} " defect closed normal Core latest duplicate template_report
