Check for main fleet before sleep time issue

Hi, I've lost my fleet a few times because of this mechanic. The bot is searching for the main fleet way too early before going to sleep mode. When the main fleet is on FS and arrives a few minutes before sleep time bot chooses another smaller fleet for FS instead of scan 30sec before going to sleep mode for the main fleet. Please fix it ASAP or add option to auto fleetsave from specified coordinates!
It's not hard to implement auto fleetsave for more than one fleet, please we need that feature!
