I once had told Caffeine not to sleep my 2014 MBPr when the lid was shut and later put it in my backpack.

Why the frak doesn’t the laptop have an over temp shutdown feature? iPhones so, trying leaving one in the sun for a bit.

Caffeine shouldn't prevent it from sleeping anymore anymore unless you have an HDMI plugged in it.

Yes and Macs have worked like that since the PPC days. Display closed + no external display connected = sleep. Removing said display will also make it sleep.

I guess it's a bug or some monitoring service that crashed.

Perhaps it was Amphetamine with the relevant setting to prevent sleep with built-in display closed.

Any fullscreen apps using the GPU will prevent a MacBook from sleeping when the lid is closed. Games, YouTube, even some GPU-heavy apps can prevent it from sleeping.
