I'm still on night 3. I nearly tossed my laptop so I decided not to play for a while..lmao
I just got past it. The trick is just to keep an eye on Springtrap, lure him between easily two switchable cameras and just keep doing that. If you get an error, check the vents immediately after you've fixed it. If Springtrap isn't there, seal whatever vent he's in, lure him back and then continue until you succeed.
