Building extension doesn't output iphoneos-64 in the obj folder

hi all

i followed all the instructions for building a 64 bit extension.. I even took a ready made one and tried to rebuild it
sometimes it outputs everything perfectly and i even use the rebuilt extension (like i did when i updated and fixed the notifications extension)
other times it doesnt work properly!! absolutely random!
So when it's not working properly, it outputs the correct ndll files but the libnotifications.iphoneos-64.a is identical as the libnotifications.iphoneos.a even with the same size etc. so it gives an error in stencyl
i notice that the libnotifications.iphoneos-64.a is always bigger usually.

i really didn't change anything, it just randomly switches from working properly to not.

so when i delete the obj folder.. and it regenerates it i notice there is no iphoneos-64 folder (when its not working properly)

any ideas why that's happening?
Thanks!

for some reason... i was trying that after a restart and it didnt work
but after i tried running my game on stencyl THEN doing the build for the extension it worked.. in case it happens to anyone.. maybe that fixes it

now suddenly it stopped working for i386 ... did anyone experience something like that?

it literally compiles new files (without changing the code) at various stages..
like if a compile failed in stencyl because of the architecture issues a new set of files is generated when i run the build!!!
so weird.. now i cant create extensions anymore.. the extension ive been working on the past weeks is messed up

this error appears when i run the game with the modified extension:
