If a mod changes a map tilesheet, the changes aren't visible until you exit and re-enter the location.

See sample save and Content Patcher pack. When first loading the day, the footprints and beer cans are there; after leaving and reentering, most of them disappear. Ideally the change should be visible immediately.

MouseyPounds reports it's fixed for townInterior but still happens for walls_and_floors.

Repro steps:

1. Install the sample content pack.
2. Load the sample save.
3. The strip between the rooms won't change until you re-enter the location.

Works fine in the latest SMAPI dev branch, MouseyPounds confirmed with an alpha build.

Done in develop for the upcoming SMAPI 2.7.
