CSS Issue when loading a Bootstrap 5 template

I had similar issues though it seemed to be caused by having multiple projects open in Pinegrow at one time. Could that have been your issue too?

Unfortunately the bug report has never even been acknowledged - either on that forum post or via the direct mail i sent to support. Am feeling that Pinegrow (for me) is way too buggy and way too unsupported to be a viable app to progress with.
