Great to hear! I am using Launcher version of plugin with UE 4.16.3. I can get the GitHub version if necessary.
I wouldn’t mind having to reassign the attachment indices manually each time ( since if you have to do the Rebuild function anyway, it would not be a big deal to calculate the particle indices), but it is not critical for my project : I can split up the rope into two, one VDRope with the particle attachments, and one VDDynamicRope continuing from the end of that.
