Hey jota_kinabalu, thanks for reaching out about this; we're sorry to hear you're having this crashing experience. You will want to start by double checking your system specifications against our system requirements for ACO before performing a cache clear by deleting browser data and cookies; running another browser has also been known to help. You can exhaust all the typical sources of performance issues by utilizing the steps listed on our general PC troubleshooting FAQ and by performing a re-installation of the game. The last step will be to go through each step of our ACO performance FAQ to resolve any major performance issues you may be suffering. Ultimately, if you are finding none of this resolves the matter for you, you will want to look deeper with an agent of ours by creating a ticket with our support team. Best of luck and happy gaming!
