Stadium bug?

So i don't know what happened so i thought I ask here and see if i can get a answer. I was playing a tank in stadium and I pick my boost and we won the first round easily. Second round I'm brought back to the character selection menu and had to pick my character again. So I do but the armory isn't available at all and my original upgrades are also gone it seems. So i have to start the second round with just a base character and it goes as poorly as you would think. I'm also not in the team display. Does anyone know what happened or if I did something wrong or if I can fix it next time?
