I got this GL_INVALID_OPERATION error while rapidly going through portals and observing the fix for MC-180.

I was idly breaking a portal and relighting it in very quick succession and when I went back to my starting portal, I noticed that a turtle nearby had a corrupted texture. I unfortunately forgot to get a screenshot, but this error

[Render thread/INFO]: OpenGL debug message: id=1282, source=API, type=ERROR, severity=HIGH, message='GL_INVALID_OPERATION error generated. Texture name does not refer to a texture object generated by OpenGL.' 

was getting logged over and over.

I am unable to reproduce, but I figure that the error message and my explanation may be enough to look into a possible cause. 

Also, I don't know if this is related, but I was doing this right after I was testing my other reported bugs. I reproduced the bugs and tried the portal traveling again, but I still couldn't reproduce, so I'm not sure.
