So I'm experiencing a weird glitch...my character is level 5, about 23 XP from leveling up to 6 and I need to take the INT Implant to be able to get the Educated Perk. My INT is currently 3, when I talked to Usanagi the first time I went there the dialog option was available for the implant as "Can you make me smarter?" I thought it cost 2000 caps, so I picked that, after finding out it was actually 4000 (3000 with the discount giving for low INT) I went back to the Gun Runners sold enough of my equipment to afford it, then went back and now the dialog option is gone. Any ideas of what's happening here?

It also appears the problem persists when raising or lowering my INT by 2. I did this via Mentats and Moonshine putting my INT at 1 and 5 both times nothing work, however I reloaded my save, killed a few things took intensive training, increased my INT to 4 and the option became available...I'm going to try and temporarily raise it by 1...

EDIT: After messing around with my stats I finally managed to get my INT to 4 with a -1 / +2 boost. STILL doesn't work. This complete destroys my character build so I guess I'll just start over...though I love New Vegas I swear this game frustrates me to no end sometimes.
