Why does Compiling Shaders show Huge Numbers?

So this seamed to have started after the 4.1 update

I have a shader which when i made a change in the previous version of the engine would count down from around 350 when compiling only after i hit Apply.

Now when i edit the shader or any other shader it counts down from 1,000-1,700 as soon as i make any chhange, assuming this was a bug i tried reconnecting a node that was already connected over and over and each time i did the shader compiling count would jump by 1,000…

Is this a known bug or am i the first one to encounter this?

A fix would be greatly appreciated.
