Blender stops exporting after certain animation

I have been using blender alongside unity for a while now, and it has been working fine most of the time, but every once in a while i find this problem that i just can't solve. Here's the thing

I've recently added a new animation to my blender file, and now every animation that comes after that one (alphabetically) stops exporting, that last animation is exported but it has errors and doesn't work well in Unity. If i delete the animation, then every other animation is restored, but it happens a lot.

As far as i know, this must be a blender problem, because when i toggle the console window in blender while exporting manually to fbx 6.1 ASCII it tells me that every animation is being exported until it gets to that last animation, and every other animation fails to be exported and it just stops, if you could help me with that i would really appreciate it, i really don't know what could be wrong with that particular animation, they are all done with an armature and bones. I know this must be a blender issue, but it would really help me with Unity, So thanks in advance!
