Error Log: !query -> pending (Happening again!)

Sorry I have to make another question for this issue. The last time, it spontaneously dissapeared so I couldn't grab a screen shot but it's back again. I'm not sure how to reproduce this or what the error even means. Please help me if you have any clue about this. It's not world ending because my game still runs fine but it's definitely something that I want to solve.
