Can anybody help?, I get this error with any object using round

Date: 13-Oct-21 15:39:35
An error occurred in Round Push Pull
Error in Analysis of model

undefined method `normalize' for nil:NilClass

I can do this with a new document and a cube and I get this error or in an existing model.

Amazing!
Thanks for letting me know you fixed the extension store issue

That's a really great plugin, I had some trouble getting it to work also: I had to disable a bunch of plugins for it to work, so there is a conflict somewhere.

For reference, here is the error I was getting
