Hi guys!
I have small problem.

I have main scene, play game scene, help scene.
When i'm switching between scenes and returning back to main scene (sometimes) font characte not displayed.
Whats happen? and why it's occur sometimes? I can't understand.

On main scene am using MenuScene.class
//code
private Scene scene;
private MenuScene menuScene;

//How am loading font
fontTextureAtlas = new BitmapTextureAtlas(512, 512, TextureOptions.DEFAULT);
font = FontFactory.createFromAsset(this, GameConstants.FONT_ARIAL_BOLD, 70, true, Color.BLUE);
loadTexture(fontTextureAtlas);
loadFont(font);

//set child scene
scene.setChildScene(menuScene, false, true, true);

Between schen swithing i always unload all textures and claer all variables.
