when i updated the discovery trigger in the template, this trigger in the host not updated.

for example i updated:
1. dependings - they are updated on template, but not updated at bound hosts
2. generation: once or many times - they updated in both places, but sending email notify happens on each recieve new data;

This problem started in version 3.1.0 and after upgrade to 3.2.1 is not lost.
perhaps the new version is not it will manifest itself as before.
