Game Hangs when mod has ogg file in a "Sounds" folder.
Had to manually kill the game (it is unresponsive when loading the mod)

Log shows:
Uploading Crash Report
UriFormatException: Invalid URI: Invalid port number

followed by more info, but it is easily recreated

Copied file "ma_action_feed.ogg" from Gamedata/Sounds folder into a Folder named "Sounds" in a mod.
Start game with mod checked (or re-load the mod) and game hangs.

A) same ogg file in "Data" folder for mod gives no issue (probably is ignored)
B) empty "Sounds" folder in the mod gives no issue (guessing that issue is the file and folder combination)
