I have encountered this thrice in Sandbox(I play there mostly). When the gold box notification comes my game crashes :( I lose all my progress and also miss the gold.. plz fix this
Your graphic card is too old and also have a very little graphic memory. It's a miracle you can even load the battle.
Please provide your game logs.
K. I will send it soon!
