I've been working on decorating my farmhouse lately and I never liked how the spouse room walls and floors always clashed with what I wanted so I just downloaded Ran's Spouse Garden and recolored it to match my interior colors. I loaded it up and it all looked all nice (aside from Sebastian's 14 heart frog display just hovering there) so I did the normal reload for Custom Furniture packs to work and the garden was replaced with a basic empty room. I'm not too sure what could be causing this issue as I have about 80-something mods and SMAPI logs zero errors.
You mean exit-to-title? I'm not sure there's a way to fix stuff acting weird when you do that, at least not on your end.
That's unfortunate, I guess I'll just have to wait until Custom Furniture is fixed to use the garden then.
