Hi.
Finally the bug that sometimes caused unexpected bumps an jumps in animations was found and fixed in the code. To those who wish to have the fix available right away, you can download an ArtOfIllusion.jar here: http://kuukahvila.com/artofillusion/temp/
It was compiled with a newer Java than what usually is used in the official releases, so I can not 100% guarantee it's compatible with everything else.
If you wish to know about what happened, have a look at this discussion on the SF-forum: https://sourceforge.net/p/aoi/discussio /b34171a2/
Have fun!
