When using WorldEdit with modded Minecraft, I'll often run into the error:
Invalid data value 'x'
x being a high number.
For example, when trying to paste in some HS Track from Railcraft:
[502:816] - I'll get the error:
Invalid data value '816'
I've also tried using the BlockId I got from Minetweaker with
/mt hand but got the same error (because this fixed it for another person). I used the BlockId
Railcraft:track:816. I really just need a way to do this so if it is easier to use another mod please let me know.
