None of my sporecasts will download completely. I removed the game and the user settings, and tried it again. Both times I had the cache increased to 4096MB, but it has only reached 64MB. Following the early termination of downloading the sporecasts, it downloads about 20 or so duddy creations such as early creatures and boats-- stuff I'll delete because it's terrible. Why is it able to download duddy stuff and not sporecasts?

Here are some examples:
The Snouters: web - 6; game - 4
Myth & History: web - 1,858; game - 624
Zoology: web - 1,092; game - 222
Prehistoria: web - 3,864; game - 377

Creations from as early as June of 2008 and as late as today are displaying properly, as are C&C, complex, and bots, so I'm not sure how it's deciding what creations to leave out. I do know for a fact that there are not very many captains or adventures in these sporecasts-- in fact, the snouters sporecast that's missing 2 creations is one of creature stage creatures only and one building, all of which I made.
