This is more of a crafting/city improvement suggestion rather than QoL, but as that forum is currently disabled...

I would like to see a city expansion, perhaps to the Seekers Garrison, that adds a team of logisticians/"cleaners" to the Garrison that enhances the monetary return of expeditions. Once unlocked, this would be a constant, passive effect to expeditions.

Unlocking this "cleanup" team would allow for a percentage return of gold based on the items/monies/consumables that were left unclaimed on the ground... initially unlocking at, say, 15% of their overall "sell" value. This effect could then be improved to 30%/45% with upgrades, with the final upgrade perhaps providing a very small chance to find a high quality, legendary and/or unique item that the hero may have "overlooked" in his expedition.

Cheers.
