All of our packs are designed to work with Minecraft Bedrock Edition.  Our packs are made for vanilla style gameplay.  No additional experimental toggles should be necessary to utilize our Add-On Packs.  Please note Dead Score, Snooze Pack, and AFK Slack Pack will not work individually with other packs that utilize the player file.  We have added these in a combo pack for your convenience.  Current Packs are tested and working in 1.21.1.  These packs should continue to work into the future but check back often for our latest updated packs.  Most packs get updated within one week of a stable game release.
