[h2]Changelog. Update 2.0.263[/h2]

[h3]Improving spawn[/h3]
- Added trees in the Abandoned Village on Starting Island. Increased trees number and spawn rate in other zones of Starting Island.
- The spawn rate of copper deposits in an abandoned mine has been significantly increased.
- Slightly reduced the density of animal spawn on the starting island.

[h3]Server optimization[/h3]
- The logic of mobs has been greatly optimized
- Now mobs will move much less often, which should make it easier to attack them, especially with increased ping.
- Optimized fragments of calls to server resources.
- Optimized the logic of objects falling asleep on the server and their network detection.
