Running as root has netted identical errors from two of the four games when people were uploading/downloading turns:
Code:
open("/home/kenlon/dominions3/savedgames/itwasadom3game/ftherlnd", O_RDONLY) = -1 ENOENT (No such file or directory)
I'm running Ubuntu 10.04 x86-pae, so it's a 32 bit system. I'm running out of ideas here.
