Tag value change event on trial expired state

Hi,
Im developing a software using the ignition 8.0 free trial.
Even if the trial is expired, script binded to my udt tags value change are working.

I have 2 bool tags, when the first one value change to true I make an insert on a db, when the second become true I perform an update.
Everything work as expected, but sometime the update is not being processed.

Is it possible that when the license expire, some script are not being execute?

They are not supposed to execute when the trial expires.

In my project I have about 300 tag with value change script attached, and no vision or perspective.
I’m not using any transaction, only Phyton and named queries.
Everything work as if ignition was in free trial even when it is not, appart from that strange behaviour that happen sometime.
It may be a bug then.
Thanks
