Look, I wrote in a line of code which auto reboots the code if it crashes but nothing can be impossible. I can ensure you that the APi if crashed will become online again in under 10 minutes. If it does not, you can always join the support server and ping me or dm me the problem.
Image endpoints are rendered through a package named canvas. Canvas takes time to process new image requests. The image endpoints are fast because the code caches the generated images. It is taking time/not loading means there is something wrong with the code.
Yes sure. You can join the support server and suggest there or click here.
No it isn't and am not looking forward to make it!
