I have this problem since the 20 day and almost 29 slaves. It is almost imposible past for the next day. The energy do not recharge and the next day report never comes. Somebody now about this?
If you are playing on Windows, then there should be 2 windows: the game and a terminal that looks like a DOS-prompt. The terminal will display error messages from the game. Please put the terminal somewhere on the screen where you can see it when the game starts, try to end the day and keep and eye out for any error messages. Either type the entire error messages or screenshot the selected window(Alt + PrtSc) and post them here.
If you are playing with any mods, please list them. If not, then I invite you to try my bugfix and improvements patch on the Strive Discord (https://itch.io/t/284398/discord), search for "change log". A slightly older version can be found here: https://itch.io/t/667993/leos-mod I don't know yet if it will fix whatever your problem is, but it does a lot. The Discord is also a great place to get problems fixed quickly.
