I went out on a long expedition in my big vehicle, and accidently forgot to unload my 25 potato seeds that I made into 40% and 50% bonus seeds before I left. Not a big problem, until I find some potato seeds in a abandoned structure. Now the new seeds have the bonuses, and the ones I brought are reset to 0% bonus. Somehow they switched.
I now only have 5 seeds with the high bonus, instead of 24. Not a good trade... I had the original bonus seeds in my inventory when I picked up the new seeds. After I got back to the vehicle to unload, I noticed my old seeds had lost their bonus, but also that the new seeds had a bonus that was the same.
