After creating this topic I realized I didn't have an AddBlock Exception for GB and after I had made one the problem seems solved, so I'm just writing this to help out anyone else with a similar problem.
I am having this weird experience where after the video is done it replays but without any picture.
Furthermore it doesn't stop unless I refresh the window.
This is happening in basically every GiantBomb video.
I'm using Chrome with two extensions: AddBlock and Google Document.
