I tried earlier to regen the pollination package, but it didn't seem to have an effect. I hate doing it, since it takes so long to repopulate, and the imported creations on the planets change. Spore has a terabyte drive allocated to it, both program files, cache and storage.
The last time this happened was when I was logged on the spore site during database maintenance, but there's no way for me to test that.
Thanks for thinking about it for me. I'm not well acquainted with reinstalls off the origin site, and hoped this was a common quirk. This far I have two creations, made a year apart, and neither has been added to the sporepedia. There were at least two regens during that time, plus clean installs.
