Don't know if anyone else has noticed, but the Lua API documentation is broken.
Solved - wasn't aware of it. Not sure why this happened in the first place, so it might disappear again - do you have any rough idea when it stopped working?
From my browser history, last time I've visited this page was in April...
I first saw it about a week ago, but just shrugged it off.
Wanted to read it today :-)
Thanks for fixing.
