I did steps 1-3 before posting here :) I am on production server. A detailed description of the issue. The more information you can give us, the better able we'll be to fix the issue promptly! Not sure what else I can tell you that I didn't above. The campaign is on my account and is entitled "Lee's Mythic Kingmaker". Step by step instructions on how to reproduce the issue. 1 go to campaign details for my campaign "Lee's Mythic Kingmaker" 2 click on the invite players link 3 copy link address for the "Share Link" 4 Send that link to potential new player 5 get email from potential new player saying they get an error when trying to join campaign Your computer's settings (A good place to find this info if you don't know it is Support Details ): Web Browser Google Chrome. Interestingly, when I use firefox, I get a UI textbox to enter an email address, so that might work. Will try that in a moment. Nonetheless, the actual Share Link is still giving the player an error, which is the real bug here. Browser Version Version 43.0.2357.130 m Operating System Windows 7 64-bit If Javascript is enabled Yes Your anti-virus software Kaspersky AVG List of any browser add-ons or extensions enabled Since I actually did read steps 1-3 previously...none! You can optionally include screenshots by using the "Attach a File" link when submitting a post. Here is a screenshot of the invite players dialog. Note the distinct lack of any UI to actually enter any email addresses to invite. Yes, I blacked out the share link in the pic, but will PM it to you if needed.
