Minecraft Forums

hi minecraft forums, I wanted to know what is wrong with my minecraft! close to my house (which is VEERY BIG) they are many mountains and jungles, what is happening is that when i fly to the jungle just before getting inside the minecraft crashes, but this just happens when i try to get to he jungle flying from my house to the jungle because when i get to the jungle using another road nothing happens! and it also happens when i step on the top of a mountain what is also close to my house, and what surprises me is that when i try to start minecraft again i have to do it wit the "s"(in order to get out of the zone where i crashed) key pushed down because it seems that just when i am in some specific coordenates or some specific zones (tiny zones aproximately from 3x3 to 6x6 blocks) the minecraft crashes without exeption. when i get to that places the minecraft stops with a saving chunks screen (without loading bar) followed to a black screen. in order to get a crash report i checked out the forge log and that was what i found
