This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches.

Subject: [PATCH] Bound Treasure Maps to World Border
|
|
|
|
Make it so a Treasure Map does not target a structure outside of the
|
|
World Border, where players are not even able to reach.
|
|
|
|
This also would help the case where a players close to the border, and one
|
|
that is outside happens to be closer, but unreachable, yet another reachable
|
|
one is in border that would of been missed.
