Sounds good to me.
I´ve got a small thing to add: Imho it would be a lot more effective, if your bot would fly a circle after collecting a box and afterwards continue to fly in the direction set on the minimap.
As you well know, most boxes spawn in field-like shapes. Unfortunately, a bot that flies a straight line often does not notice the whole field but a few isolated boxes.
A circle could help to increase the percentage of collected boxes in a field.
Additionally, it would be a lot more diffcult for human players to identify a cloaked bot as such- possibly preventing a few kills.
Keep up the good work!
