if you need me to get a log and see if i can reproduce it again just let me know
my friend also generated a world and had the same thing happen

HEE doesn't generate anything in the Overworld.

i know but being that the heads are from HEE i didnt know where else to report this

i know its a compatibility issue though just not sure where its stemming from

Remove batches of mods until it stops, narrow down the list and find the conflicting mod.

ok i just generated another world and noticed this this time

obsidian blocks this is at the very least something with thaumcraft because this only happens in the thaumcraft magical woods biome ill go remove more though and see if there are other mods also causing it

ok this might not be a compatibility issue with HEE because i removed some mods and this time it generated with AE2 blocks instead of HEE blocks

Sounds like some mod is using integer IDs.

it was project red causing the issue im updating to the lastest since a new update came out today and will test it to see if its fixed

ok newer version of project red did indeed fix the issue
