Upgraded from 1.6 to 1.7 & everything is missing

[givemhell]

i recently moved my 1.6 world into the 1.7 world a booted the server up with 4 mods total, for some reason ALL of the microblocks go missing when the server starts, ive also checked this in single player and without the other mods

the only thing i can think of is that the ids have been changed but last i heard 1.7 auto assigns ids i also checked configs and they are the same, im completely confused as to why the blocks dont xfer over like my other blocks

how would i go about fixing this?

@Chicken-Bones can i get some advice?

The 1.7 builds is not compatible with 1.6 at all.. There are even a few 1.7 builds, which breaks stuff with older 1.7 builds.

That shouldn't be the case, provided you ran your 1.6 world with the latest Forge and FMP for 1.6, and then with 1.7, it should work alright.
