Should we do a reset? And how would we actually do that? Is it possible to change the identification number to a long or a guid?
Map IDs are a short so you're limited to 32,767 unique ones once you hit that you run into problems. Why Mojang made it a short instead of an int is beyond me. With dupes, certain plugins that use maps, treasure maps from villagers, etc you run out of maps quickly.
Hm. This is probably not too hard to hack to turn it into an int, but it would require some patches or mods.
