It works for me on 2.1, you just need to open the zip and change the version from 2.0 to 2.1 in the info.json file like this: {
"name": "biter-remover",
"version": "2.0.1",
"title": "Biter Remover",
"author": "azaghal",
"homepage": "https://github.com/azaghal/factorio-biter-remover",
"description": "Commands for removing and disabling biters and pollution.",
"factorio_version": "2.1",
"dependencies": [
"? base >= 2.1"
]
}
