Starting at around, I guess 11:30am game time, I started having extremely long load times for pages. For me, they seem to happen when naming horses. Most of the time, the page will get "stuck" loading and won't continue to the new page. In order to get the site to start responding, I have to completely restart my browser.

I'm having this issue on both Firefox (v. 58) and Chrome (v. 65).

It's because I was trying to do things with the horse table.
