By my calculations, you got a total of +236 from upvotes and accepts. You also spent 100 reputation on 2 bounties. However, those bounties do not increase the cap for that day. According to the help center:
You can earn a maximum of 200 reputation per day from any combination of the activities below. Bounty awards, accepted answers, and association bonuses are not subject to the daily reputation limit.
Note that your reputation was reduced because you offered bounties. When someone else awards a bounty for one of your answers, those aren't counted toward your daily limit. But you don't increase your daily limit by offering bounties.
On the other hand your two accepted answers and the +6 from accepting 3 answers do not count against the rep cap. So by 23:40 (when you got your final upvote) you'd hit the cap: 236 - 30 - 6 = 200.
