This is weird. I don't remember it happening on my old install, and the c12ds installer and patch were among the few things I did have backed up so this should be the same version that was working then.
But I just tried to create a new C12DS world and got this error: (copied from the logfile .txt)
Error in: AgentManager::CreateSimpleAgent
Simple Agent:
Family: 1 Genus: 1 Species: 32337
Gallery: c1ef.s16 First Image: 0 Image Count: 1

The following sprite gallery was not found:

Users\Owner\Documents\Creatures\Docking Station\Images\c1ef.s16
It let me continue without crashing, and everything looked normal, but what's going on? C3/DS doesn't even use .s16 files as far as I know.
