Describe the issue
Prerequisite : mine a tile, until the excavator is waiting for a truck to load what was excavated. Then remove the designation. The resource disapear from the excavator bucket

Before

After (without unpausing)

Thanks for reporting but this is not really something we aim to fix. We have this way to keep the code around this simple and robust.

Yes, if you don't want to implement a job description for each resources but keep it at the designation level, that make sense too (way more complex to attach that to each resource...)
I will be cautious not to clean my mines too early then 😉
