Trying unsuccessfully to work with planes on a split/mixed layer. Thought maybe there was an issue with my plane so I tried to delete, but the tool crashes every time with error "Fatal Data Base Error Number 2017".
Multiple attempts with variations to disconnect from the net first, change layers, etc.. All fail. Is there a way to deal with this, or at a minimum to save the design without this layer and reload it?
try exporting an ASCII and importing it back,
more methods to fix this are mentioned in technote MG63822
