Sorry if I disturb one once more, but BG crashes again. This time the crash occurs when I try to load my game.

More precisely, I'm using a multiplayer game and it crashes when I click on Create Game => Load a game. Here the screen with my saves appears, but without the mouse pointer, and crashes with the error message "An assertion failed in InfScreenLoad.cpp at line 1541"

Maybe this could be easy to fix but I can't find this InfScreenLoad.cpp file anywhere and I wouldn't know how to edit line 1541 to make it work. Any idea?

I installed BGT-Weidu with BP and I could play without any issue until the Lost Island quest. Here is the crash : when I try to escape from the island on the boat my computer gets back to windows right after the area loading at the beginning of the "animation" describing the trip back. Yet I successfully did a full install of TotSC.
Any idea to solve this?
