Dynmap-blockscan is a tool that scans modded textures on the server & allows Dynamp to display them. This is a fork of that mod that fixes an index-out-of-bounds exception when loading some mods.
NOTE: This mod will vastly increase the amount of time it takes for your server to startup if you have many mods. At times, it may look like the server is has stopped launching, but it just takes that long. Increase max-tick-time in your server.properties until you no longer get errors like this: ServerHangWatchdog detected that a single server tick took ___ seconds (should be max 0.05)
