We are doing maintenance work on our servers right now. Downloads in Pack Manager are not working while it runs - you may see “Network error! Check your internet connection” or “checking for updates” when importing an item you have not downloaded yet. Your connection is fine, nothing needs to change on your side.
Items you already downloaded keep working. We expect downloads to be back in approximately 3 hours. If it is urgent, let us know in the chat and we will send you the files manually. Sorry for the inconvenience.
