i’ve added this to our public buglist here: https://gitlab.com/yourhead/stacks/-/issues/621
i should be able to fix this up in v4.1.3 – thanks for bringing it to my attention. it looks like the small difference in the folder structure of RapidWeaver Preview between RW7 and RW8 is taken into account for one of the css paths.
it should not affect the published content – it’s an issue just with RapidWeaver 7 and only in Preview mode.
