the bug is the total ammos when starting activities. its supposed to be half of the total reverve for both weapons when using double specials and its not always truth, like for The Sunless Cell GM Vanguard Alert u will start with what you had when you finished the last activity with a minimum of your magazine size and a maximum of half of your total reserve. The bug is not specific to GM's. This happens in other activities and not all GMs have this bug, but The Sunless Cell does.
