Dynmap has been removed until 29 April 2016. Now before you groan and complain, hear me out... The map hasn't even finished generating. Its a very slow process, and I'm sure you've felt the lag. You know what makes that lag worse? People in those chunks, using the map, searching for all the things to loot. So, for three weeks, we are removing the dynmap. This gives other people the chance to look in the new chunks to see what they can find. The map should only take a few more days generating, so the lag should stop soon.
