[2021] 27m lost to some kind of trade exploit? A warning.

Hey everyone. I just started playing again a few weeks ago. Last night I got scammed, and I am not really sure how. Its so demoralizing, all my profit over the last 3 weeks just gone and I have no idea how.

Situation: There was a guy at GE last night asking for help with GE buy limits (which I have done before for others).

Asked him what item he wanted. He traded me, showed air battlestaff and 96m in cash. I (very, very foolishly) spent almost all my whole cash stack of 27m on ~3k battlestaffs for him. I go to trade him, he puts up 27m, I click accept. 27m shows on second screen just fine, and then we both accept and POOF. Trade accepted, no cash in my inventory, battlestaffs are gone, and he is immediately logged out. I sat there for a few seconds utterly confused. Once I realize what happened my heart just sunk.

I know its just a game but I am not very good at it. I just got my first primordial from Cerberus and I was feeling hot. Now I am just so sad, I just logged out immediately.

Now I am broke, I have no recourse other than report for scamming (which I did). It really ruined my night last night, and I don't think I am going to keep playing. That was 1/4 of my whole bank just gone. I was just starting to hit some good loot luck too.

So heads up to anyone out there, don't trust anyone. Only trade stuff through GE. Has anyone else had this happen? What the hell happened?

If anyone from Jagex sees this, I have the guy's username although I dont know how useful thats going to be.

:(

Edit: For anyone seeing this and not wanting to sift comments, it sounds like there is some kind of a trade bug exploit that allows the exploiter to seemingly process a legit trade all the way to the second confirm screen. Once there, some people say the gold disappears if you wait long enough. But if you're like me and you take only a few seconds, and then accept, the gold will not get traded and the items will disappear. I would not recommend trading with anyone you dont know/trust 100% with any trading of any kind. GE only. Sounds like this may have been reported by someone as late as 2 years ago.

I also appreciate the people who have offered to give me gold to cover, you folks are real saints. Now that I am aware of what is potentially happening, I want to get the word out more than anything. I don't want to take anyone's hard grinded gold, and I have contacted Jagex support directly to see if they can help at all.
