"Internal error" when downloading backtest results due to using a percent sign in my backtest title.
Kept getting "There was an internal error." whenever I try to download my backtest reports. Looked at the URL of the request and noticed the way the end of the URL is formatted, which uses percent signs for other characters. Did a separate backtest with the same parameters, but no percent sign, and it downloaded fine.
Just wanted this to be brought to the attention of the devs. Definitely not using percent signs in my backtest titles again.
