This fixes the following minor issues: * Errors like "Cannot create flag (...) because there is already (...) flag" during debug startup * Unnecessary seeks during .dm* causing io reads and e.g. delays of up to 5s on x86 macOS during debug startup * Flags are now created in the "maps" flagspace, rather than globally, making them easier to clean up later * Flags now have the same size as the maps and not +1
