When you decline to help the refugee in the Refugee Chased at (Settlement) event, in the message there is a typo I think. It says "tinny speaker" instead of what should be "tiny speaker" I think.

Because of I'm not a english native, I'm not sure it's typo or not. But according my dictionary, 'tinny' describe like as 'made from tin, cheap quality, unpleasant metalic sound'. I feel it is match for screaming situation. So, I translated it like as 'We heard a scream from cheap (bad sound) speaker'. Size is not important I guess.
k2ymg is correct. It's not a bug. Thanks for reporting anyway.
