Can we just have it check if there were any similar email addresses registered with an account in the last 5 minutes or something, and you can't create it

It's not possible to register more than one account with the same email address, the more problematic bots create tens/hundreds of email addresses which are different, but similar. Many of them follow the formula of oneword_another@example.com, so I've thought about whether we should make it impossible to register with an email address containing an underscore, but as with so many counter-measures I think that might cause trouble for genuine users, so I doubt that would be a good idea.

What about email verification? If too many accounts use the same email, it doesn't allow you to create it

Hi, @Caroby. Welcome, and thanks for your contribution! I wanted to mention that cycling through buildings is already a feature available in the Autociv mod (you can get the latest version with some bugfixes here). In addition, this functionality has been incorporated into the next version of the game, along with hotkeys for constructing buildings and selecting units by class. The only difference compared to your mod is that, when cycling through buildings, the camera doesn't automatically focus on the selected building. To do that, you need to use the Focus Selection hotkey (default: F). On another note, I tried your mod, but it only selects the first building of each type that I constructed. It doesn't let me cycle through the other buildings of the same type.
