This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Interestingly, this does not happen if Mesh Around Obstacles is enabled.

Just to clarify, this is happening consistently in this one file. I haven't had this problem with other scenes.

Thanks for letting me know! This error means that the simulator is accessing memory that is out of bounds, which is a bug. Would it be possible to attach the .blend file for testing?

vmxeo commented 6 years ago

File is attached....

This was an error caused by a simple typo in the code. This fix will be included in the next version (0.1.4b). Unfortunately there is no workaround to this for this scene. I have added a custom build that includes this fix to your Dropbox folder.
