Can't see the flash during eating and amusement.

you have most likely (accidentally) activated the debug option "fast workers"

So how may I close this option?

loaded up the save for a test, it is indeed enabled

vanilla you cannot adjust that, the screen shown here is from my mod Modify Difficulty Settings, it lets you adjust the difficulty after the game was started (you will need to enable the mod, adjust the setting, save the game and then re-load it)

also do note that the "Fast Workers Mode" setting only shows up when you have debug enabled
