I have updated to latest version of the plugin (4.3.1) and discourse (2.5.0.beta4) and noticed that almost all of my topic list previews are gone 
I am able to regenerate the preview image on a per-topic basis, however this is a) time-consuming, and b) nudges the topics to the top after I update them.
Is there a way to automatically regenerate the topic thumbnails?
I really love this plugin - it’s done wonders for our forum and makes it look great. I also tried the [edit - it was a from a different author so not relevant to this discussion] TC but found it looks quite different and has less options - so this plugin still seems superior to me unless someone can correct me?
