1. Fixed a critical bug with packet spam. Now, after the chunk is loaded, the packet is sent only once per player, as it should. This will reduce the load on the connection, increase the speed of loading chunks, and generally improve server performance.
2. Fixed a bug with discoloration of the grass block when tall grass grows.
3. Fixed bug with /vivaldi reload command. Now it works properly.
4. Added compatibility with PlaceholderAPI. Three placeholders have been added: %vivaldi_current_season%, %vivaldi_date%, %vivaldi_season_duration%.
