Afaik this is the issue if you don't install the server-sided fix mentioned in the release thread.

Exact name of this "Server sided fix"

because im certain that i've tried everything maby i overlooked somthing so please post the name of this fix!

Im thinking it has to do somthing with torches! i placed some torches outside and suddenly when i place blocks on my wooden house it crashes!

Quote from Player

The server does not crash, it's the clients

Put http://wiki.industrial-craft.n…nloadfiles/Fixes/vy.class in everyones minecraft.jar

seems to be fixed for now Thanks!
