"This attachment cannot be shown at this time. Please try back later." I'm seeing this all the time when I try to download mods hosted locally onsite. Sometimes, I'll try again 10-20 seconds later and it will work but other times I just give up after several minutes due to the time it's taking to clear up. I would like to request that when you create and upload a mod to this site could you also please make available an externally hosted copy until CF sort out their bandwidth? There's a lot of good content being missed out on by fans due to being unavailable because of heavy traffic load. Thanks.
You may have more luck if you right click on the download link and choose "Open in new Tab". I've done it several times and had to only retry a few times since the beta released. Nonetheless I agree with this.
