Event's thumb image get deleted inadvertently

I have encountered a condition that the event's thumb image can get deleted inadvertently.
I wonder if this is indeed a bug.

Here is the steps:
1. Create an event with a thumbnail image.
2. Highlight that event and click 'copy'
3. In the 'Thumb Image' section of the event form, check 'Delete current thumbnail' .
4. Click 'Choose File' to upload another image.
5. Click 'Save & Close'

--> The thumb image in the previous event get deleted unknowingly. This could be dangerous if I happen to create a lot of events by copying a seed event. If I make the above mistake of checking the 'Delete current thumbnail', the the previously created event will have their image gone.

In my opinion, the copied event should have its own unique file name for the thumb image.

Hi

Right now, when you copy an event, the extension doesn't copy an image, it will just use the image of the original event. I am not sure creating another copy of the image would be the right option, so I won't implement it for now. Will wait for feedback from other customers before making final decision

So for now, if you want each event has it own image, please upload image for the copied event
