Users report that on https://community.openstreetmap.org/g, the groups list only displays the first 36 groups under certain conditions—such as browser resolution (1406x826) and having more than 36 groups—and the missing groups reappear after resizing the browser window. SomeoneElse notes the issue doesn’t occur on https://meta.discourse.org/g, possibly due to fewer groups. chapoi confirms the bug is reproducible even in safe mode, suggesting it’s not forum-specific. saquetim states the issue cannot be reproduced on the latest Discourse version and suspects it may already be fixed; the OSM forum runs the stable branch, which is slightly outdated. The problem is expected to resolve once they update to the next stable release.
