I have 9 (max) tickets. I am only in 1 of the mission summary lists (part 1).
You should consider all the parts of the summary as one post. Your name should only appear in 1 of the mission summary "part" posts, with your total number of tickets attached. example: Crushdavis-9
If i'm not mistaken, the summary shows all users who have at least 1 ticket, ranging from 1 to 9 - in no specific order. Take mine for example (part 1) you can see people having all different ticket amounts. 9, 1, 3, 7, 6, 2 etc. So if you show up in 1 of them, you good.
Your username should also be found in each of the seperate mission posts you completed, so you can count for yourself. (example mission 1, mission 3 etc) Easiest way to do this is to just search for your username on the forum and count how many you are in. good luck
