Bug Description
A few hours ago while attempting to join Hypixel Skyblock, I warped into my private island, froze for a few seconds, then the saving world animation played and the game crashed with the message "The game crashed: unexpected error. Error: java.lang.NullPointerException: Cannot invoke "com.fix3dll.skyblockaddons.features.backpacks.CompressedStorage.getStorage()" because "this.compressedStorage" is null". Once I took the SBA mod from the mod folder, I joined Hypixel Skyblock without a problem. The game also crashed when I tried using the previous version of the mod. I had SBA in my mod folder earlier and used it without any problems alongside the rest of my mods

Bug Description
A few hours ago while attempting to join Hypixel Skyblock, I warped into my private island, froze for a few seconds, then the saving world animation played and the game crashed with the message "The game crashed: unexpected error. Error: java.lang.NullPointerException: Cannot invoke "com.fix3dll.skyblockaddons.features.backpacks.CompressedStorage.getStorage()" because "this.compressedStorage" is null". Once I took the SBA mod from the mod folder, I joined Hypixel Skyblock without a problem. The game also crashed when I tried using the previous version of the mod. I had SBA in my mod folder earlier and used it without any problems alongside the rest of my mods
