I suspect I found a free-energy bug in 2.43z. In the attached sim look at the lower right corner, there are some tiny veggies (alga shellular), that look tiny even at the highest magnification (you can only see their eyes). On the attached screenshot of that area they are circled in red. Their genomes are composed only of viral DNA, which deleted everything else.
The sun is turned off, they are neither shooting nor tied. But they have 1 body and ~45-47 energy. Their energy goes down slightly, but then jumps up by about 0.4 energy which apparently comes from nowhere. At least I have no idea where it could come from. One thing I noticed is that their energy is always just a tiny bit below a whole number - 45.95, 46.87, 49.99. The jump is usually when it goes below .85-.86 of that number.
