Problems with rendering image series

Greetings fellow Dazers :D
I have a pretty annoying problem that keeps happening.
Lets say I have an image series of about 90 images (for an animation) and i start to render them with the "image series" render option. When it starts it goes great, it will render a bunch nicely and perfectly, but then suddenly it does what ever you will call this (picture attached). But if I then go out and render the exact same frame but as a still image it looks perfectly fine (picture attached) why is it doing this, and is there some way to fix it?
Hope for some help thanks :D
