I suggest that the code be modified to accumulate the results of all treasure and resource missions until the start of the player's next turn and then display ONE window that shows the results of all of the missions in total.
For example:
10 Treasure Hunt missions found 1,000 credits.
15 Scavenger missions found:
23 Durantium
21 Elerium
18 Thulium
This would provide players with information about completed missions in a succinct manner.
