# About the pull request

Notifies when intel points are maxed for non-xeno non-yautja corpses.

# Explain why it's good for the game

If we're gonna limit intel points for corpses to 50 bodies, then there
should at least be a notice sent so that people aren't trying to recover
bodies for points when it's not possible.
