Does it give you the option to continue loading the world with mismatched ids? If so, copy your world somewhere else, creating a backup, and then start up Minecraft and load the world and see what happens. If all of your things disappear/turn into sand, or if it crashes or nothing at all loads, come back here and let us know. I doubt I can actually help any problems, but more info is always a good thing.

I can load the world, but all things i built with Little Block mod is replaced through Redstone Repeater.

Thats inda the reason it is warning you about mismapped ids.

Having mismapped ids could cause issues exactly what you're refering to.

Not really anything we can do about it. Either make sure you have updated your mods properly and made sure the ids mapped properly.

Or just go with it.

Having spent the last 8 hour debugging this, and finding nothing useful on the interweb... I am posting the solution on each thread that I looked at with no answer...

 

Some mods overwrite the vanilla minecraft blockids.    Those mods do this when you start your client, even before you connect to the server.  The server then checks your IDs, and sees you have a conflict, but its with a mod that the server does not have.

 

The Normal blockid conflict message comes up when the server and the client both have the same mod or same mods and there is more than one mod trying to use a blockid, or the mods on the client are configured to use a different set of blockids than the server. 

 

In this case, though, your client has a mod that the server does not have -- and this mod has overwritten a vanilla minecraft blockid.  So the error is saying that your client is disagreing with the server about a vanilla minecraft blockid that has been overwritten by a client mod the server does not have.

 

The solution is to remove that 'extra' mod from your client.  Coping over the server configs will not help you, because the mod is not on the server -- the servers config files do not apply to the mod that is causing the error.
