And since block and item IDs are not accessible by the user in 1.7.x doing this is impossible.

On the other hand this error happens if an outdated mod is used.

Like say ... a 10+ months old beta of Thermal Expansion. Which is so old and broken Team CofH removed all official downloads for it more than half a year ago.

There's quite a number of other grossly outdated mods there.
