Carnival party quest 2 total spawn is 15 and each side is able to summon 7 and the winning team can summon 8. However, when one team over spawns, the other teams spawn gets bugged. Even when it shows 7 spawn on the opposing team, you can only see 4 to 5 monsters and this gets irritating. ...not only is this irritating to me, I'm sure it is annoying for newer players and others who also partake in this party quest. This glitch ruins the experience of Monster Carnival party quest 2 for players that accidentally over summon.
If its a bug, you should write this post on the bug report thread instead, it will be easier for admins to find this and take care of it properly. Or maybe just make @Evan do the hard work and move the thread
