We finally managed to reproduce the problem and it is now fixed! The fix will be part of the next beta / release candidate of 3.0.0.

We cannot reproduce this problem. We have added some logging code to the Modeler so that if it happens again, we'll know some more. This logging code will be part of the next beta/release candidate of 3.0.0. Please let us know if it happens again with this new version.
