I just placed a bounty on an old question of mine. Silly me, I used backticks in a LaTeX way rather than a StackExchange way, so the formatting of the bounty description is messed up.
I don't believe there is a way to fix this. Of course, we don't want the bounty conditions to change midway through the week, but shouldn't there be a short period during which typos can be fixed? There is already a similar period during which a question can be edited without an "Edited" message appearing.
