I have just upgraded my mcp to 7.19 (MC 1.4.2) and downloaded the new forge versin for mc 1.4.2.

now i replaced every error i could find. and was error free after a few fixes.

now when i start minecraft it gives me the following error:

and a couple more of these for the same reason.

i am probarly missing something obvious here but does someone knows how to fix this?

Do you have a new furnace/machine in your mod?

Because the newest forge has a new way  of handling a container.

Have you added the mod name to your @Instance annotation? Like this:

@Instance("ModId")
public static BaseMineConomy MineConomyInstance; 

The ModId needs to be the same as the one in the @Mod annotation. Hope this helps!

Code: [select]

@Instance("ModId")

I tried that but it didn't work.

I do have containers in my mod...

do you know how to handle them now?

Its your @Instance

Theres no way around it, write your @Instance annotation correct, with your correct ModId
