I noticed that if I left the server (fewer chunks need to be loaded if nobody is there, leading to slightly faster map building), when I came back I had no clue what the current progress was at because the bar was gone. This update fixes that, as well as adding a xx.x% value to the title of the bossbar, giving you an exact value of the current progress. Now if anyone joins they can see the current progress of the build and know exactly where it is at.
