Subeta acting weird, lag big time, images not loading, quickstock not working...and more of alike...Or is it my comp? (which I doubt, since it's working on every other site)

Everything except the quickstock isn't working for me. So your not alone. :)

Mine sometimes takes longer then usual to load the images but otherwise it's just fine.

Mines is working perfectly.

subeta often has downtime because of random stuff that builds up in the server. c: most likely, the server is just being slow (it happened earlier today). sometimes, it even crashes.

so you're not alone - you would just have to try later.
