Thanks! I’ve added that to the tracker. This is an odd one, I think an update changed some behavior - because I’m now getting a different result on my travel laptop (I’m taking a short holiday) and remote controlling my work setup. I’ll investigate further for B2. I’m leaning towards a source control merge issue, it looks like I have a branch merged on my work setup and not on the travel laptop - the source isn’t quite the same.
