Problem with mod work in local game

[BedrockBlyat]

The mod does not work correctly in a network game (if the client does not have the mod, players spawn bedrock and stone, which is visible only to them, and not to the host), and if the mod is present, players simply cannot interact with the world in any way (open chests, furnaces, etc., while when breaking a block, it simply becomes phantom for them, but for the server everything is fine)

You can try to have the mod in both the client and the server. I'm not sure if it works though, but anyways the mod is intended only for singleplayer.

Unfortunately this mod can't work properly in multiplayer, because the packet protocol only allocates a long value (64 bits) for block positions, which is not enough when we extend the world border up to the 32 bit limit.

This issue doesn't occur in singleplayer though, because the packets don't need to be translated in this way.
