cloaking devices don't let you hear things being spoken

It's like you're in a container!


Also, people with mesons can see people with chameleon.

The mesons thing is intentional, or at least some of the admins are aware of it and think it works well enough to be considered a feature. But that's just from memory, I could be wrong or that could have changed. It would make sense, since if you're a chameleon you're blending into the scenery, so meson goggles, which reveal things hidden in the walls and floors and such, would be able to see those.
