Off by 1 minzoom?

[four43]

When constructing a themepark theme, I have the following conditional for my way:

if a.minzoom < 10 then -- XXX TODO some kind of off-by-one error here?
    themepark:insert('railways_low', a, t)
end

I see a bunch of ways in my railways_low table that are of minzoom 10... There are no other references to this in my theme. I'm very curious about that "some kind of off-by-one error" here line? This seems impossible and I'm just as confused as that comment.

Thanks for the excellent project.

That comment is in a few places in the Shortbread configs. I don't remember why I wrote that, but apparently I thought that there might be a problem. I, or somebody else, has to go through there in detail and look at the code and the Shortbread spec and figure out what's what.

I believe I ran into the same issue, it was very odd. My railways_low table is full of minzooms of 10. I had to go double check Lua didn't do a silly <= automatically or something like their index start of 1 :P
