About this project
What does One Block - Chest Version add?
The update is now added and there were quite a few changes and I hope that all of you love them. Be sure to check out the channel log for more info. Try not to add to many mods that give a bunch of items it may crash the game or give you chests filled with dirt. This confuses the chest. The wayto fix it is remove mods that have a high volume of items, or a bunch of or remove a bunch of smaller item count mods. Then you might have to start a new world. I am trying to figure out a fix.
# One Block - Chest Version
One Block - Chest Version is a Minecraft Forge 1.20.1 mod built around a custom animated chest and an evolving One Block survival experience. When starting the game you can play on a normal world and have most of the features, but to have all of the features you will need to go into world select when creating a new new world and chose the One Block Chest Version. A really big thing is this mod should work with all other mods. I haven't ran into any problems yet myself but can't run through all of them sorry. I have been trying the pretty basic food and animal mods so far, but will continue other very popular ones as I go.

- Regular Minecraft Leads can attach to Endermen and tamed Ender Dragons

FYI
If you have any questions at all please leave a comment as I will be checking them frequently and I will be very happy to help. Also I will be doing updates but probably not for a few weeks to a month unless there is something urgent that needs to be fixed. I am currently working another mod called that I hope to have available within the next month or two. i hope sooner but it is just me working on them, I do not have a team lol.
