Direwolf20 1.0.11 Server Issue

[JKapGaming]

Hello everyone,

I just recently updated my Direwolf20 server to version 1.0.11. When I try to connect to the server, it gives me an error stating:

The following microblocks are not installed on this client:
tile.railcraft.brick.nether

How do I go about fixing this? Is it a server issue? Is it a client issue?

Any help would be greatly appreciated!

make sure your client is running the same version (do a force update to be sure)

I can ditto the error. Here's the funny thing: It only occurs on my son's laptop. If I run the client on the PC that is also running the server, there is no error but my son's laptop presents the error despite his client being an exact copy of my own.

What is the fix for this given that disabling all nether materials in the railcraft config does not resolve the issue?
