I just downloaded and installed WL 13.0.30, but I need to revert to 13.0.20 quite urgently due to a bug I’ll explain later, if it isn’t present in 13.0.20. Could I get a download link for that, please? @PG1
Unfortunately previous versions of WaveLab 13 are not available for download.
The only chance is your own download directory, where the SDA stores the download packages. In case you haven’t deleted it you should be able to find the previous releases in there.

That’s why I’m asking @PG1 for a download link, I’m sure he can organise one. I don’t have the installer for 13.0.20 anywhere on my system any more, and this bug I’ve just come across is very serious. It started occurring just now when I downloaded and installed 13.0.30. I want to make sure that it’s not present in 13.0.20 so that I can properly report 
Steinberg downloads are not under my control. I have asked someone at Steinberg, and he should answer me later today.
What exactly is your problem?
Thank you!
The issue is a loud burst of audio (buffer eject?) every time I stop playback when running audio to my analogue chain via a reference track. It is a bit hard to explain so here is a video: Unique Download Link | WeTransfer.
Just wanted to check that it’s something that started with 13.0.30 and not something that has gone wrong with my interface etc.
The signal chain is: Reference track → Additional output bus (CHAIN) → DA/AD → Audio track that is monitoring the input signal.
I doubt that anything has changed in this area between version 13.0.20 and 13.0.30. In any case, it will be interesting for you to try with the previous version.
I think I found the bug: somehow the other reference track I’m using for the client reference mix was also being driven into the chain, so when I stopped playback, that unloaded something into the chain as well.
So user error in the end, but wouldn’t have thought about that if I didn’t randomly see it just now!
