Subject: [PATCH] BGE: fix [#35447] LibLoad Meshes and Scenes causes crash of
 blender

KX_BlenderSceneConverter's destructor freed the contents of several std::vectors without removing those contents from the vectors. Later these vectors are iterated through. Making sure the vectors get cleared solves this problem.
