Bug/Issue Error log, and all I wanted was a good latte

So I did my best to follow the install instructions for the Coffee Shop mod, but I seem to have crashed my game. I have Stevens crops which seems to clash with JsonsAssets(plants and such) removing Stevens crops seems to have done more harm than good.

I have a Crash log https://log.smapi.io/r5RSWu7Y if anyone can decipher it. Id much appreciate it. I do have the sinking feeling that I may have to start an entire new game for this addition to properly work, but if there are any alternatives I'd love to try one.

 

Looks like my save file contains some plants/machines that have different uses or don't have any use with the Artisan upgrades

Does Stardew Valley have some Kind of save file cleaner?
