I'm getting the following error on certain cases which I can't reproduce constantly:

NoesisGUISystem::Error on [.\Gui\Animation\Src\Storyboard.cpp line 334]
The target name 'IndicatorIndeterminate' cannot be found in the xaml namescope

The only relevant clue I've got on it is that it happens only after a few loading / unloading sequence of the xaml sources. I have multiple scenes on my system that are loaded and unloaded by the user and all of them share the same xaml source.

Please advise me where should I focus.

That name is used in our styles by the ProgressBar template. I suppose your xamls contain any ProgressBar that is using the default template. You could create a new template if the default one is failing as a workaround.

Could you please create an issue in the bugtracker and attach the error dump. We will try to reproduce it and fix it as soon as possible.

Thanks, I just opened a new issue.
I'm using a progress bar in my main xaml file that gets loaded and unloaded.
Note that I'm setting the progress bar value manually during the last 5 minutes of my level to display a cool down style widget.

Thanks, you can follow the issue status in our bugtracker.
