i only play on the browser (can't download the software), and play solo only, not on the servers. i have no mods, haven't imported anything. but my world on creative mode starts loading but my stuff is gone, then it stops loading and i get the server tick loop error. why is this?
No idea if the applet installs the .minecraft folder to your computer or if its browser-side, but if it does, try going into your .minecraft folder and deleting your minecraft.jar (In bin folder).
Play in browser only, get tick loop error
