I don't know if its any indication of Mo Creatures.. (Who knows.. it might).. But I know someones posted this link earlier

And.. Strangely enough.. it does have Mo Creatures listed on it..
Ive been messing around with Mo Creatures since 1.45.. And Honestly.. I'd given up on it.. The custom spawner squelched any mobs not setup with it (ex.. Angry Zombies on Thaumcraft.. Mystcraft Ages with no monsters.. etc.etc).. However.. the newer version might seem to have fixed things.. I was playing around with my own 1.52 build while i was waiting and decided to test it out .. I was amused when I ended up tossing Chococraft into the mix.. and when i rebuild the config file.. I had Chocobos listed in the config.
As far as building your own Pack..Its possible.. but not without difficulty.. (IF you can do it.. and cant wait for the official FTB packs.. then do it..You will get a greater self of self accomplishment and achievement than by using a prebuild.. You will Also learn what FTB is going through trying to get everything setup and in order)
As it has been Said before..Things don't work properly between everything yet.
I Tried building out a fresh build of 1.52 last night.. I found a Dev version of IC2.. It worked.. I added Buildcraft.. It worked.. The moment i added Forestry.. Everything died.. (And yes.. I know how to google errors).. didnt really find any Solutions other than "Its Development.. What do you expect"..
Anyways.. FTB is not the only one fighting with this 1.5 transition.. Tekkit.. God.. I looked at the new 1.5 tekkit.. Its missing so much.. Divine RPG.. They have been going back and forth for over a month trying to get code adapted.. At this point.. i'm coming to the conclusion.. that 1.51 was one of those major Game breakers for everyone.. And while yes.. a large chunk of the developers have updated to newer codes.. The Larger more complex mod packs.. Are still fighting with it... as far as RP2... Eloraam has a life.. Anyone who has their priorities straight will realize that having a life trumps anything electronically delivered.
