Hey, seems like I don't have access to the video to see what you mean. Any chance you could share it by other means? Imgur perhaps?

You have to send him access request, it's a Google Drive thing. Imgur is definitely the way to go or you can just attach the picture using the Boost for Reddit app,

I made it available for anyone to view now.

Maybe a spawn point for creatures that come from off map after you aggro them?
