FIXED FLOW

Account login -> choose existing BG2 campaign (Shadows of Amn / Throne of Bhaal / The Black Pits II) -> play that campaign video -> Create Multiplayer Game directly -> create/import character -> save/export directly in active account characters directory -> Ready -> play that created multiplayer game.

Removed the custom Baldur's Legend in-game menu that could appear as a black screen when its custom mosaic was missing.
The game UI now uses stock BG2 campaign resources only.
