It happened occasionally in early IDL seasons (meaning ZD had it as well). So blame Randy. His coding style is notorious for being &#039;unique&#039;.<br />[/quote]<br /><br />To be specific, when you want to center your view, internally ZDoom sets the viewpitch to -32768.&nbsp; However, this viewpitch was sent to the server without modification, resulting in...well...that youtube video.&nbsp; Kids, don&#039;t use [url=http://en.wikipedia.org/wiki/Magic_number_(programming)#Unnamed_numerical_constants]Magic Numbers[/url] in your code.<br /><br />The bug had apparently been in csDoom and derived ports from the beginning.&nbsp; I believe the bug was fixed in ZDaemon 1.08, and Sean went ahead and [url=http://odamex.net/svn/log.php?repname=Odamex&amp;path=%2F&amp;isdir=1&amp;peg=3321&amp;sr=3321&amp;er=1&amp;max=1&amp;search=]nipped it in the bud[/url] just now.&nbsp; Thanks to everybody who helped us out by bringing it to our attention and providing us with demos.
