Sometimes. Happens to any VST. I have just reproduced with Dorico 6.1.10.
- Launch Dorico
- Open a project (that created long time ago)
- Wait until all the VSTs are loaded
- Go to Play tab
- Click add VST
- At this point, if the bug is hit, things have already went wrong (the index in the window title is incorrect)
“18 - Kontakt 8” is the one I just added, but window title shows “19”.
