This still happens in 5.1.1. Seem to happen when I use migrated assets or copy paste a large number of assets at the same time? Does not happen in 5.0.2. Resaving the world data layers and the World partition minimap allowed me to at least click on the world partition tab as before this would cause memory crash while attempting to allocate memory? After saving all building
works fine but the minimap build is still not working. It is stuck on processing cells?
