Higher quality components require transport drones of the same quality. I'm not sure if this is intended. Also, higher quality drones have no advantage over the previous ones.
Because this project was upgraded from version 1.0 through modifications, the architecture is still designed as it was when there was no quality. It inherently has flaws that make it difficult to achieve the functionality you mentioned. We can only use transport drones of corresponding quality to transport items of corresponding quality. I will refactor it to implement the functionality you mentioned after this version stabilizes.
