This was a long-standing bug since Luma3DS v8.0. If you changed the homebrew title and didn't immediately reboot, then the ExHeader during termination would not match the ExHeader that was was used for loading the process, and thus sysmodule process refcounts would get all messed up. The obvious solution to this is to ensure no application is running while changing the hbldr titleID (hence the changes in custom PM). This was quite possibly one of the cause of homebrew failing to load when using N3DS H&S.
