post debug log

did you read the link? the code you use has nothing to do with Networking Edit: show the Ether class (the implementation of your Capability interface)

Enchantment#getMaxLevel in your case: Enchantments.SILK_TOUCH.getMaxLevel()

you need to post the link here

you need a custom Network packet which you send when the capability data changes on server, and in PlayerLoggedInEvent, PlayerEvent.PlayerRespawnEvent and PlayerEvent.PlayerChangedDimensionEvent

did you sync your Capability to the client? since rendering is client side only but it seems so you set the value only server side

you can use https://gist.github.com/ for large text files

is this the full debug log, make sure it is, if this is the full debug log post launcher log aswell

One of your mods requires Track API. Unfortunately the mod does not properly indicate this dependency, so the mod simply crashes instead of Forge showing a helpful error message.

this is not the debug log, the file you should post is called debug.log if you using CurseForge you need to enable the debug log in the settings

What are you talking about?

is this the full debug log? since it simply ends and does not contains any error

you can use https://gist.github.com/ you can upload the file by drag and drop there

post debug log

could also be a problem with Radium

the mod is there me.jellysquid.mods.lithium.common.shapes.VoxelShapeSimpleCube

Remove Lithium also do not use magic performance mods

post new debug log

update to the latest version of Forge

you need to return true in #stillValid for your own Block, since the vanilla Menus does only support one Block you can copy the vanilla logic but you need to use your own Block instead of Blocks.CRAFTING_TABLE

yes

show your Menu class

you need add a AttributeModifier with Attributes.MAX_HEALTH in this case

why are you sure that it is a vanilla server? post debug log and show the run.bat file
