Ok, so first I would like to ask people not to put insane amounts of lava everywhere, they have a habit of causing lots of lag on the server
Also, people have been reporting strange glitches that have been occuring, for example you may find smooth stone floating randomly on the surface or rivers or large bodies of water, as well as some strange water blocks and POSSIBLY lava blocks that appear in strange locations
The cause or reason behind this glitch is unknown, I'm a bit confused by it, but it's definitely a server glitch or a corruption of data. If you find lava that is disturbing you, remove it or contact a mod.
On the bright side however, we now have a live map of the server. You can view the map anytime you'd like in the browser at this link
http://23.95.30.171:8123/ (No need to be logged into MC or anything!)
If you want a minimap, that's a client sided mod, IE: You (as the client) will need to download the minimap, I can't give you the minimap through the server.
NOTE: It will take a little while to render the whole thing, so if you join and it's black with splotches of terrain, just wait a bit while it renders
