Some changes in Starblue Valley alpha aren't applied in Content Parcher 1.3 alpha.

See:

• content pack
• verbose log (failing entries have BAD! in the name).

Also this (patch: sprobj: stick debris):

Reposted due to wrong account. I put together a new content.json that supported some additional variations I wished to offer (support for magimatica's Hudson Valley chickenhouse for Shane and a blue spruce colorway for the pine tree). It dramatically increased the number of patches I had to do for each {{season}}_outdoorsTileSheet. When I tried it in game, almost nothing loaded. Is it possible that the system isn't handling the large number of edits well? I've attached the new content.json for your convenience.

Issue 1 and 3: some changes aren't applied

This happens when we change a texture after the game has started using it. SMAPI has logic to update references to it, but it doesn't cover all core assets yet. I created Pathoschild/SMAPI#459 to address that in 2.5.4 before Content Patcher 1.3 is released. I'll keep this open until the 2.5.4 beta is available.

Issue 2: red overlay over sticks

That's normal. The patch is overlaying { "X": 96, "Y": 192, "Width": 32, "Height": 16 } from assets/Cursors.{{language}}.png, which looks like this:

Followup: issue 1 was because the content pack mistakenly targeted spring_outdoorsTileSheet twice and left out Maps/spring_outdoorsTileSheet.

Should be fixed in the next Content Patcher beta build.
