Dear 343,
I wish to report a bug that i just came across.
When going into career, and then Halo 2 achievements, i did not see High Charity achievement. Therefor i selected it, and this is when i got the message popup, “$DIALOG_NO_DEEPLINK_CLIENT_BODY”.
Also, the maps will not record that they are completed in the missions menu, even tho the achievement is given.
