Download some nodes with tags, like housenumbers or bus stops 1. Save the layer twice 1. lock one of the layers by adding `locked=""true""` to the header 1. Reload the locked file 1. Create empty layer and add some node 1. Configure some nodes to conflate from the unlocked layer to the new layer 1. Set the locked layer active and select the identical nodes as in the unlocked layer 1. Open conflation configure dialog and close without changes 1. Select all matches in the conflaction panel and conflate ==== What is the expected result? IAE ==== What happens instead? Conflation should take place in the configured layers and it should not matter which layer is active or at least no exception. ==== Please provide any additional information below.
