Issue is back, I don’t think the model choice affects it - reasonably sure I’ve seen it occur with Auto and Composer 2.5 when in Plan mode.
Note: This is a WSL setup.
@ianm If you have any more steps that can help us repro, that would be great. I’ve tried on my Windows box with WSL and still never end up with this message when iterating on a plan/building! Would love to get to the bottom of this.
