Structural changes when editing and enabling library types
When structural changes are made to library types and you undo them manually (not by an undo command), dependent types are set to the "Processing" state during the enable. If you continue without editing the dependent types, the following error message is output when you compile the dependent blocks: "This interface contains changes that are not compatible with the block/type used. Please edit this block."
