Bug / Crash One Particle acts like kinematic

[josemendez]

Looks like a call to PrefabUtility.RecordPrefabInstancePropertyModifications(); is missing in the attachment's editor , (ObiParticleAttachmentEditor.cs) line 109. Should look like this:

void OnParticleGroupSelected(object index)
        {
            Undo.RecordObject(attachment, "Set particle group");
            attachment.particleGroup = index as ObiParticleGroup;
            PrefabUtility.RecordPrefabInstancePropertyModifications(attachment);
        }

After this change, select the attachment of the "start" particle group to CoffeeMachineOutOfOrder, and re-select the "start" particle group (click the particle group dropdown, and just select the same particle group). That will fix the issue.

Will add this fix in the next update. Thanks for reporting it!
