The Locator Bar should show Illagers/Raiders during raids

Problem: When I played with my friends there would often be a situation where there's that one raider that is just *gone*. Apparently, that last raider ended up in a cave. And naturally, that last raider doesn't show up when using the bell to make raiders glow, because that raider is simply too far away.

Solution: During raids, the locator bar should be utilized and it should show all the raiders. Maybe give the raiders a unique icon to differentiate them from players, also.
What? You say part of the fun is looking for the raiders? Seeing all the raiders immediately is too OP? Okay, how about only the last couple of raiders are shown in the locator bar?
