My first suggestion: is not to put the excavated land immediately in inventory, but to have a choice between putting it in inventory or for example on the neighboring sector of the earth.
The second suggestion: have the ability to throw out of the inventory immediately all the land (a whole cap), rather than 30 pieces. This is not comparable to the realities of life. Would you really throw out 30 pieces of land in the realities of feudal life? I think the people would rather have thrown out the whole land at once and not the parts
