I tried out the new auto-start logging to see how logging works in 3.5.2 snapshot...
I typed a simple string into the chat window, ended logging, exited module.
I then loaded the log file... I was presented with what looked like a saved game, and the chat window was empty (excepting the standard loading dialog).
Shouldn't all the info that goes into the chat window, whether from player typing chats or game generated info be saved in the log?
