 ## 6. CompletableFuture and Optional basics
 - HuskSync's API methods often deal with `CompletableFuture`s and `Optional`s.
 - A `CompletableFuture` is an asynchronous callback mechanism. The method will be processed asynchronously and the data returned when it has been retrieved. Then, use `CompletableFuture#thenAccept(data -> {})` to do what you want to do with the `data` you requested after it has asynchronously been retrieved, to prevent lag.
-- An `Optional` is a null-safe representation of data, or no data. You can check if the Optional is empty via `Optional#isEmpty()` (which will be returned by the API if no data could be found for the call you made). If the optional does contain data, you can get it via `Optional#get().

 > **Warning:** You should never call `#join()` on futures returned from the HuskSyncAPI as futures are processed on server asynchronous tasks, which could lead to thread deadlock and crash your server if you attempt to lock the main thread to process them.

-What about modded items? Or custom item plugins such as MMOItems or SlimeFun? These items are **not compatible**—check the [[FAQs]] for more information.

-*Purpur's custom ender chest resizing feature is also supported.

-†This is intended for servers that have mirrored worlds across instances (such as RPG servers). With this option enabled, players will be placed at the same coordinates when changing servers.
+* What about modded items (Arclight, etc.)? – Though we can't provide support for these setups to work, they have been reported to save & sync correctly with HuskSync v3.x+.
+* What about SlimeFun, MMOItems, etc.? – Yes, items created via these plugins should save & sync correctly, but be sure to test thoroughly first. 
+* What about Purpur's custom ender chest resizing feature? – Yes, this is supported (but make sure it's enabled on _all_ servers!).
+* What do you mean by location syncing? – This is intended for servers that have mirrored worlds across instances (such as RPG servers). With this enabled, players will be placed at the same coordinates when changing servers.
 
 ### Map syncing
 Map items are a special case, as their data is not stored in the item itself, but rather in the game world files. In addition to this, their data is dynamic and changes based on the updating of the world, something that can't be tracked across multiple instances. As a result, it's not possible to sync unlocked map items. Locked maps, however, are supported. This works by saving the pixel canvas grid to the map NBT itself, and generating virtual maps on the other servers.
