Negative mutations and spontaneous dropping of stats during breeding

[76561198056354571]

I use the ASM program to read the statistics of my dinosaurs and encountered a number of unexplained situations during breeding. In all the manuals I read, it was said that mutations in dinosaurs occur only in plus, but I had multiple cases when descendants received a negative mutation. That is, the stats of the descendants were lower than the stats of both parents. I first came across this when breeding low-level toads. For example, the father had 7 units of damage, the mother had 5 units, the descendant received 3 units of damage, and in some cases even 0. There were several cases of stat increases and color changes, but the mutation counter did not change. I thought that this was a special case, since when breeding more traditional low-level species - pteranodons, argentavis and others, such errors were not observed. However, now I began preparing to kill bosses and breed dinosarves of the 135-150 level - pteranodons and megatherians and faced the same situation. Descendants do not inherit their parents' stats. Pteranodons have had several cases of spontaneous zeroing of stats. The parents had a speed of 10 and 13 units, the descendant had a speed of 0, the mutation counter did not change. And this suddenly turned out zero stat was passed on to descendants. In megatherians, I had to reset the pregnancy in females several times, since they inherited a lower level of health than their parents. One would think on the touch of the ASM program, but I checked all the stats of dinosaurs in the game and it really is. Has anyone encountered this and how to deal with it. I play a solo game.
