And WebView version can be out of sync with Edge (it's a bit of a pain to keep them in sync) - no idea if that causes this kind of issue (combined with MSVC mismatches).
I redid the drums in the end and tweaking a few other parts when I created the album/EP on Bandlab:

Thanks for the constructive criticism all.
This sounds like you are using a workspace: you've edited one of the factory ones and use that, then the installer comes along and replaces the factory ones, resetting your changes. Use a user workspace and they won't get overwritten.
I think that's the best track of yours I've heard - it's hauntingly familiar (and haunting!) in a really good way. I'd mix the lead "theremin" with a little less top end and a little more delay/reverb, but apart from that, I think it's a great mix.
I agree about the drum part. I was finding it hard to find a good 3/4 pattern in my usual arsenal and my drum programming skills are...rusty to say the least.
