How comes the resampling process did fix it until I made a change to the scene?
But anyways, there are no words enough to thank you both for your awesome and quick help. I was literally struggling with this for a good amount of time! But like you said, some hints/tips would really be a nice addition to the visibility tool now after this incident. 
The more odd question remains when and why did I even use the tool in the first place… Maybe I’ll just blame it on the cats.
But really, thank you both and till next time! 
Sincerely,
