I feel rather silly asking this, but ... [title] "Where Are Vendetta Logs Stored?" Thank you very much.

It is a file called errors.log inside your Vendetta package. For Macs, right-click (or [control]-click) the Vendetta package and pick "Show Package Contents" from the drop-down menu.

Windows...?

[edit] my bad, it' "control-click" on a Mac.

For Linux it's in ~/.vendetta
For Win it's the dir you installed the game in (usually C:\Program Files\blah blah)

for windows its also in the errors.log in the vendetta folder.
