it is crashing a few seconds after the dimension finishes building with the error below, i have changed dimlets around a bit - but it's still going down.

i have broken all the rf tool machines and replaced them as well.

when i load back up - get the error on the dimension "dimension information missing"

version is FTB Infinity with 2.63 (updated manually)

in order the dimlets are:-
Biome extreme hills dimlet -:4
Controller Single Dimlet - :166
Material Ferrous Ore Dimlet - :516
Terrian Flat Dimlet - :407
Time Noon Dimlet - :486

I notcied that the error message says there is no biome controller?

-- System Details --

So far so good, tested over the w/e, and that crash appears to of been fixed.

Yes, I'm aware of this bug and fixing it at the moment. In 15 minutes or so a 2.64 should be released with this bugfix.

Great to hear,

Also crashed after taking out the biome and controller as well.

Let me know if you need any testing done.

yes, it even crashed without specifying the biome or controller but it was still related to that. I just released 2.64 and I couldn't reproduce the crash anymore. Let me know if that version works for you.
