the problem is i changed to 1.2.5 a few hours ago and built alot of stuff, but when i rollback ro 1.1 it doesnt aply to 1.1

Hey guys, so my first question is, is it a good idea to play with the 1.2.5 version of tekkit? because i noticed all mods are woriking even if its not rec. but i guess i found one problem in my world wind mills won't work. i dont know whether i do something wrong because i place them as usual but they got no wind power at all
