[Drupal composer.json (fix for insane conflicts, among other things!)]
"merge-plugin": {
"include": [
"core/composer.json"
],
"recurse": false,
"replace": false,
"merge-extra": false
},
Add "sort-packages": true
to the config section (just to stay organized!)
Until twig/twig gets updated, add it to the conflicts section:
"conflict": {
"twig/twig": "2.7.0 || 1.38.0 - 1.38.2"
},
