Nvm. It works now, I guess I just need to restart the Chrome. But heck, the same old error still happens: "Attempting to reconnect to storage server". I wonder how I can fix this?

Hello, lordhersey, thanks for the help. I will try to fix when I have times. Well. Why the loading error still exists, I thought someone would fix this issue.

Never expected someone to reach lv 99 before tbh. Well yeah, people said I shouldn't be worried about memory leak. So what things are leaked in greenfoot? List?
