Instead of World Anchors etc. we are using a custom plugin written by KaiNoMood called BetterChunkLoader
This section will attempt to help you understand the mechanics of it and how it works on our servers
DeVco uses a custom chunkloader plugin which gives each player a chunkloading allowance based on their rank (for details see the rank section) and is created by right-clicking a placed block of iron with a blaze rod. These chunkloaders only work while their owner is online and are known as regular, “online-only” chunkloaders. Special diamond chunkloaders are created in the same way but with work while their owners are offline, known as “always-on” loaders. All other chunkloaders are disabled.
These chunkloaders are activated as soon as they’re placed and the area they load can be adjusted using their menu interface which is accessed by right-clicking the block. They can be disabled by mining them, by selecting the option in the chunkloader menu, or by applying a redstone signal. You can see a list of your placed chunkloaders using “/bcl list own”. There are no fuel requirements or other resources required for chunkloading.
Extra allowances for online-only chunkloading may be purchased in the reward store. Always-on chunkloading, however, is not freely available to players as online-only is and must be purchased from the reward store either individually or as part of a VIP package. Chunkloader allowances cap at a maximum of 75 chunks for both types, so keep this in mind when buying from the store.
In summary there are two chunkloaders, online-only and always-on. One is made by right-clicking a placed iron block with a blaze rod, the other a diamond block. Diamond block loaders are always working and require purchase from the store.
This is the amount of Online Only and Always On chunks you are allowed to have loaded at once. These are generally dependant on which rank you are but additional loaded chunks can be purchased from your servers reward store if you wish.
