Is there a way that they don’t disappear since the regPoint is outside the view ? I mean all the Sprites totally disappear as soon as their center are out (but not akll the Sprite).

I know that there has been a similar bug that I believe was recently fixed. What codebase are you using? Try it again with the latest code from the _release_ branch of the GitHub repository, and if the issue remains, please file a bug report ASAP and we’ll fix it before 4.0 goes final. Thanks!

There’ve been a couple of reports on this issue, each with different causes. All have been fixed, as far as I can tell.
