I can't cut trees in love shack and wild deeps please help
Those are two very different problems depending on where you are in the game.
For the love shack, you either need to have a Hatchet in your inventory (which is a tier 3 weapon; the ability to get that through Emily's shop
just became available in v0.16, so that's a ways off) or have the Cumhaill Accord so you can borrow their axe.
Which is separate from the Repairs Part 1 task; I know it's a bit arbitrary, but that's how it is.
If you're in the back half of Repairs Part 1 as your current story task (specifically, the "Cut Down Stripped Trees" step), only those wooden pillar-looking things can be cut down. You can't just cut down any old tree. You also can't cut them down after you complete the Repairs Part 1 task.
If you're not at that step but you're out of Scrap Wood, you probably need to talk to Phoebe. If you need to talk to Phoebe (both Ella and the Task list will tell you if you do), go into the study and select the Chat option.
If you chose to skip repairing the floors yourself, there's a chance you ran into a surprisingly specific bug that someone else reported recently. Most of that conversation is on the previous page if you want to check that out and see if that's the issue you're running into. If it is and you don't have an earlier save to revert to, I can fix your save manually if you send it to me. Just remember to include both the numbered save file and the global.rmmzsave file, or I won't be able to load the numbered save.
If you modified your save file to give yourself more Scrap Wood, that likely caused a similar issue and the same thing applies. If you don't have an earlier save to revert to, I should still be able to fix it manually for you.
