There is no notification of this. Since it is a bug it is not known to EA, and if it was it would be fixed and no notification needed.
How after 6 years of playing I can tell you key areas where you will be logged off.
You may be logged off if:
- You've created a creation in a certain stage, I.E creating a creature in the creature stage or creaturing a vehicle/building in the Civilization stage.
- Playing an adventure with Spore Galactic Adventures expansion.
Remember, if you're playing in the creature stage, make sure you log yourself in after every-single time you create a creature, so if you mate and evolve your creature, you'll need to log yourself in an share the creation online, because if you don't the next time you evolve again, that creature will be overwritten by the more highly evolved one. So by making sure you log yourself back in after every evolution of a creature you make, you won't lose that creation.
It is an annoying and tiresome way, but it is the best option that I can offer at the moment, once I have fixed the "0 Adventure Play Bug" I will request a bug fix on this too.
Just to let you know, I am pretty good in asking EA/Maxis to fix these, I myself have requested two bug fixes that are now fixed. These are:
- Sporepedia broken search
- MPN Script fix bug
Hopefully this helps you.
