Same here with the JSON error. I noticed that the Mythkeeper settings JSON was empty and filled it with these settings (I left out the tag info though):
{
"basicInformation": {
"name": "Whooplaah - Cliffs",
"version": "1.0",
"author":{
"exists": true,
"name": "Whooplaah",
"url": "
https://www.patreon.com/whooplaah",
"donationURL": "
https://www.patreon.com/whooplaah"
},
"tagLine": "Modular cliffs, canyons, plateaus, and valleys.",
"commercialUse": true,
"commercialURL": false,
"license": {
"hasLicense": true,
"type": "CC BY 4.0",
"localFile": false,
"externalLink": true,
"commentary": true
},
"tags": [
]
}
}
Repacking it into the Zip file and adding the asset zip to Mythkeeper normally adds it without error, and the asset image, patreon link and commentary links work as expected. It looks as though the leading spaces are removed with this post, but it should still work.
