Was this bug also in V6.39? I noticed a sharp increase in production estimates when I upgraded from V6.39 to V6.43 when using detailed electrical calculations due to module layout with optimizers. I ran an old variant in the new version to compare, and saw "Near Shadings: irradiance loss" decrease from -17% to -9.4%, and "Shadings: Electrical Loss detailed module calc" decrease from -6.7% to -2% (this project is in a very shady area). The resulting production estimate difference is %15, and I would like to make sure the new result is accurate before I finalize my recommendation. Thanks.
