I recently just did 5 bootcamp maps with 12+ people and they never counted please help

Were they all in the same room? The first map you complete in a bootcamp room doesn't count (as a way to deter room hoppers).

Were there 5+ people in the room with different IPs? If everyone was connected from the same place then it won't count.

You may want to report this in the Bugs forum if it persists, or ask about it in the Q&A Thread if you're curious why something isn't working as you expected.
