Buildings rarely share nodes with highways; when they do so they're not ususally on the same level as the highway e.g. the roof fo a fuel station. Hold alt in ID editor to prevent your cursor from snapping to nearby nodes. If you want to unglue nodes select them and press g. ---The issues (yellow triangle) in the bottom right should give you a heads up on some common potential errors. Know that sometimes the best thing to do is to ignore the issues if you don't know how to address them rather than making things worse, but checking what's there before uploading your changes or submitting a task can help you catch some errors you may have made while mapping.--- For my resolution see Changeset: 163225068. Please keep this feedback in mind when contributing in future. Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon. You can find events here https://osmcal.org/
