map ending before time limit / rounds

[payling]

I recently setup a TF2 srcds server and on some maps my server will decide to change the level to the next level in the rotation for no apparent reason. I was just playing on my server and it happened again on pl_badwater. It seems to be only happening on capture point maps directly after some point on the map is captured. That's the only pattern I've noticed so far. Yes, the timelimit has plenty of time left...and no.. the rounds arn't up so the map should not change . Below is my current config in regards to map changing settings.. I recently installed sourcemm, but I believe I was having the problem before.
Last night I was playing with almost a full house (24 players) and it started doing it, 2 maps in a row, then the problem disappeared for the rest of the maps that I played.

I managed to check my log file after the pl_badwater match today. (See below) If you notice the point captured was not the final point, point 3. The game ended right there... Is mp_winlimit 3 work funny for cp maps? I'm new to the whole srcds scene so I was just assuming it meant 3 rounds of pl_badwater and not 3 cap points...

Blue reached the winlimit with 3 wins. Rounds or timelimit do not matter when the winlimit is reached. Point's captured count as a win. Adjust your winlimit, I use mp_winlimit 0.

Yeah.. I didn't realize that each capture point counted as a win. For now I just set max rounds and win limit to 0 and my map limit to 40 so that all maps will play 40 minutes no matter what. I plan on setting each individual map winlimit once I find out how the scoring works. If someone could point me in the right direction it would be helpful. I googled for a good half hour and did not find any convincing answers as to how points are awarded for each game style.

Thx for your input
