Rudder

I had a directive made under a given technique, which was used in a rule (created via API).
It happens that it was made under the wrong technique, so I tried to create a new one, using the expected technique.
Of course, it did not work since their was already a directive with the same name.

I deleted the old one, created the new one and.... generation brakes.
In the rule page, the old directive is still listed as "in error" under the rule.
See the screenshot below.
