Bigpicture plugin - is there a way to delete a timeline whithout deleting the items affected by it?

[Clara Agostinho Pinha]

We have bigpicture plugin installed in our project at the company I work for.

I accidentally clicked at bigícture and created a timeline that affected the whole project items' “start date” and “End date”.

Now even if I edit those dates manually, it will go back to the date I accidentaly added at bigPicture.

If I try to delete this timeline I added at bigpicture, it will also delete all the items which are below it.

How do i delete this timeline without deleting the tickets?

PS: since i did this, bigpicture plugin doesn’t load anymore, so i can’t even take a screenshot.
