Are the command blocks on a quartz floor? Congratulations! This is where the magic happens! All my code is right there.

But to solve your problem, I suggest deleting the map from your saves folder and re-downloading it.
Let me know how it goes!

Are you talking about this map or the Order of Herobrine map? In either case, there should be a button above the door leading into the castle that you need to hit with an arrow.

Hope this helps!

Yup, I coded it all myself. Took me a while. Did you enjoy it?

Yeah, sure! I can tell you how I made my map downloadable. So basically, I got an account with mediafire, a free file sharing and storage service. I choose the basic (free) package so they can put ads when someone downloads my map, hence my warning comment in the map description. This option makes storage and file sharing totally free, tho. After that, I just uploaded my map into their storage and copied the link to the map file. Then, I just pasted the link in the part of the map submission page on Planet Minecraft called "Alternate Download" and you should be set!

I actually ran into the problem of my map being too big for the Planet Minecraft main map upload section (it had a max of only 15MB, and my map was 90MB) so I had to resort to mediafire.

Hope this helps!
