There hasn't been an update since october. This is probably dead. You can probably make the trailer -> house transition work if you used ALL to condition check for the vault bundle being complete and then apply tile edits based on that (would be a lot of tile edits though) I still don't know why people are bothered or scared by/of using tide
To be honest, I have too many ideas for mods, and most of them only involve editing .png files, so I don't think I'll bother working with tide or making smapi mods before I'm done completing all my other 'easier' mods.
