In the new version I don't see my Duplo bots when I zoom out all the way (size 10). Admittedly, they are tiny, but they were still visible in 2.43.1d as tiny specks of white (eyes?). Now it looks like they don't exist until I zoom in significantly. Did you change the way the bots are drawn? A bit annoying, now I can't cast a quick glance at the sim to see how things are going. The numbers on graphs don't give this information, because they don't tell me how the bots are distributed - they could all be clumped in a corner or they could be spread widely.
