Hi. We are using Unlimited Addons for a project and we think we discovered a bug. To reproduce:

1. Create a new Addon with Items
2. Add an "image" variable to the Item HTML
3. Add a thumbnails variable (eg. {{ item.image_thumb }}) to the Item HTML
4. Save/update the Addon
5. Use the Addon on any page with WPBakery page builder
6. Add values for all variables and save 
7. All works fine, as you would expect
8. Go and edit any value of your Addon in WPBakery, save again
9. Now all {{ item.image_thumb }} variables lost their values and simply produce empty strings

This is a rather annoying bug which might prevent us from using Unlimited Addons for this client project. Thank you in advance for checking this out.

Cheers, Georg

For everyone running into the same issue – this is our current (dirty) workaround:

{{item.image|replace({'.png':'-200x200.png', '.jpg':'-200x200.jpg'})}}

We discovered Unlimited Addons uses Twig, so you can use pretty much all of Twig’s features – in this case the replace-filter: https://twig.symfony.com/doc/2.x/filters/replace.html
