  • Thanks for the example, I located the error and fixed in svn. It got introduced dec 21st, and it's a very bad error... shouldn't be in a release.

    Basically it means that any undo with physics in Blender is dangerous. Don't do this, recompile or wait for us to update...

  • Thanks for the reply Glad i could help out. I love using Blender it's a great piece of software i use it every day thanks to you and all the blender team for all the hard work. Glad this was a serious bug that was caught earlier rather than later.

  • Argh sorry, my bad and the worst timing right before a release!

    The code that caused this is now cleaned up and shouldn't cause any more problems.

  • Thanks Ton. I was worried that i had to close the report. I can't find any where to do that. Will the report be closed automatically or do i have to close it? If i have to do it how do i go about it ? Thanks.
