To be quite honest I have not checked compatibility of my library with versions 0.4.15 and 0.4.16. I do know it's gonna break with versions beyond 0.4.16. I'll keep you informed.

I'm able to reproduce the same issue with a map generated on 0.4.14.
It is trying to load a block but is unable to do so. So it keeps looping and trying to load. The issue is that there are no blocks to be loaded on my side. Did you ever generate some?
This commit should change the script to detect the absence of mapblocks during the lighting test and abort that unit when there are none : 8bac60a. Let me know if it fixes things.
