Halo, I'm facing a problem about the key not showing in dopesheet after I hide/unhide the attachment in version 4.2 & 4.3 (beta), but the function and animation is working just that I can't see it. This usually will occur after I hide/unhide many attachments (maybe more than 8), but other skeleton in the same project with less attachment changes still visible.
Not sure is it bug or I accidentally off the attachment layer in dopesheet? But it looks fine In 4.0 & 4.1. Thank you very much!
Here is the video for different version:
