In a reply from mrangel he said
Can you share your game so I can take a look at it? It shouldn't be too hard to figure out what is causing this problem.

How do I do that?

You can publish a game on the site and set the privacy to "only people with the link"; which means you can show it to whoever you want but it won't show up in the site index or on your profile. You can then replace it with a more complete version whenever you want, and release it properly when it's finished. However, the downside of this method is that you can't actually delete a game from the site (though I think you can ask one of the admins to do it for you).

Or you could upload it to a site like file.io, which allows the recipient to download it once and then deletes the file again. The disadvantage of this method is that someone who doesn't have the desktop Quest editor/player won't be able to test your game. (I can't use the desktop version because I don't have a Windows PC, but can often figure out problems well enough by looking through the code)

Hi mrangel.
I prefer not have have my unfinished adventure code go public so there does not seem to be any way of getting the code to you as I would have tell you the link which everyone would see.

However I'll try and work out what the problem is in my code. There may have some extra test code that I forgot to remove in my adventure that's causing problems. I'll try and do a tidy up of the code which might help.

Thanks the telling me about the file.io site, very useful for sending larger files to others.
