As the title is written.
I had rejected a flaw earlier in my game because I was not confident in my familiarity with the game, and so any permanent negative modifier turned me off out of caution.
But now that I have been playing for awhile I have been found myself wanting to receive that specific flaw prompt again to accept.
I had searched online for the same question being asked, but I have read conflicting statements of "yes you can", and "no you cannot" on receiving another prompt for a previously rejected flaw.
Hoping on the off chance a staff member or someone with similar authority on the subject could clarify.
