sonic bats in solb

[Tarathiel]

so today there is a particular bat near where u go down to get to freeti that i cant seem to get a good hide against... i can sneak past all the other bats just fine but this one always aggros... when i target him and move away he will con indiff but if i get to close it will change to ready to attack... anyone else have any problems sneaking around sonic bats? it should be noted that i passed this same bat yesterday with no problem.. whats up with that?
