The game badly needs a way to be able to sell Lored's, I have 100% softlocked my game by over-leveling sand. I get 1 humus every 5 seconds, and I need 49,000 to get my sand to run again. All for 4 tasks are 'make sand', and the upgrades I have available require sand or glass.
Not sure if there's anyway out, I can't see it if there is.
