Not sure how often this will come up, but this is what happens to me.

When I try to attack a rat, I end up trying to attack myself.
If possible it might be best to have mobs first in the target "list" ?

If we change the search order in the room for , then 1., 2., etc will change, too. We nearly always have more than one keyword for any mobs, and I'll make sure the rats have another keyword, too. Sometimes it is "small" or something like that. You will also be able to target a rat by using 2.rat.
