I had in fact placed an Iron Lamp on part of my farmspace--specifically the northern portion of the map, up the stairs. As for save editing, I don't know how--I saved to files one and three, if that matters. I didn't know that about the trees! I've only ever gotten apples before. Thank you so much for continuing to work on such an engaging little world.

Save editing is changing save files using a 3rd party software, I thought it might have something to do with it but I guess it didn't. Thank you for the info regarding the lamp, I'll play around with it and try to figure out what's happening there!
You can get apple and orange seeds from eating the fruit very rarely, and because both apples and oranges can be purchased from the vendor as well, it is actually possible to have both tree variants on your farm too!
I found the issue, for some reason if you had a Lamp turned ON and tried to save on a different map, then your save got deleted instead of saved. The only way to fix this is to turn off all lamps... and preferably pick them back up, after that the save function will work normally again.
I will have a more direct fix for this in the next release!
