Hm. Wanted to check out that hwd but was blocked from here, and the site had no non-JS download button anywhere.
Maybe post it to https://issues.hedgewars.org ? Would help in tracking anyway - you could also detail where it occurs in the demo

Bug confirmed. I laughed. The bug is that you can teleport with hog into land when clicking in the gray area of a world wrap map.

I posted the bug here: https://issues.hedgewars.org/show_bug.cgi?id=247

I have extracted the demo file and uploaded it in the bug report as attachment.

Thanks for the bug report. But please use less awful services when uploading files the next time, it's painful to download the files from there.

I recommend you upload demos here: https://hedgewars.org/demos

This bug has been fixed!

The bugfix will be visible in the next Alpha release and version 0.9.23.

Yea! This bug was little annoying

Wow
Amazing kind of bugs xD
Just why... why I never knew that, before this :O
