RS graph/price glitch?..I'm confused...

So, this morning (around 6:30 est.) I wet on runescape to buy a rune scimitar for f2p bounty. I decided to look at the grand exchange database to see if I should buy it now or wait a bit. When I opened up the rune scimitar graph I saw this and got confused this...(picture below)...

Is it a glitch? Might it be that when the grand exchange was updating the graph got messed up? I'm just confused...

 

this happend to me b4. Gmone scarf were 10 gp ea i tryd to buy them but i dident got 1

 

Do they buy in-game for that much? Or is it just the graph database that's screwed up?

 

They don't buy in game for that much I checked...so I guess it was a small glitch...

 

its just a small glitch u cant buy anything,.....i had once with addy scims for 5gp

 

wtf? i though u were confused about the way it looked but idk about the G.E, i nver use it

 

Blame the support.
You have to refresh the grand exchange plenty of times just to use it.

 

Hm, never seen this happen.
Quite unorthodox if you ask me.

 

Might be a merch clan dumping there item?

 

Lol, if a merch clan was dumping there, it'd wouldn't go down to 10K.
