Kind of not tech smart so will explain this to the best of my ability. Haven't read or heard of this happening so wanted to let admins know and have other ppl share if this happened/happens again. Hopefully not

So I went into the barracks through the cave portal and everything was fine, until I tried to go back to the caves through portal. The webpage refreshed itself and started a download like I was installing something, thinking I accidentally pressed a wrong button- I manually refreshed the page & tried the forest portal and same thing happened. I then tried to exit the portal room to the barracks main page and it just refreshed the portal page and started another download. Also- the downloads when opened, popped up a notice about "something's gone wrong" and just out the outline of Sylestia, no details, but I could see the clickables for your profile and notice info that's in the top right corner of the site. I wanted to screenshot but I dunno how >.<
After closing all the 3 downloads I tried to just leave the barracks completely by clicking the World Map link and exact same thing, it refreshed the portal page and then opened a download. At this point I was definitely panicking thinking that I broke the website and in my panic decided to press the Stable link to just leave the entire map section alone. That worked! Brought me to my stables with no problem. & from there I was able to re enter the world map> LG > barracks > cave portal. Everything is working as it should now.

I am unsure of what exactly was going on or would have caused it. Nothing should be downloading like that. There are various image assets and sound files that load when first entering the Lost Grove if you don't already have it locally cached, but that should just happen in the background and not be something visibly happening on your end. Perhaps some sort of oddity or setting was changed/messed up that caused something like that. And if it did, it's possible the rest of the script files broke because they were waiting for the download to end.

Either way, just a hard refresh of the page and/or reboot of your browser should fix it if it happens again.
