Burning escorts is a classic, well-known bug, alternately frustrating or hilarious depending on how immersed you are in the simulation. I've seen it in multiple mods, and it probably happens in vanilla too. I can't speak on it too authoritatively, but my understanding is that it can happen to any small ship that's damaged by heavy seas. If large enough waves swamp the ship, it takes flooding damage, which is why it generally happens to only small escorts and little steamers.

Chalk it up to the enemy's poor seamanship

There are other similar ship self-destruct issues you'll run into. Don't be too surprised if that troublesome 20k ton "Modern Passenger Liner" spontaneously scuttles itself, which can even happen in calm seas. Sometimes subchasers and armed trawlers can spectacularly blow themselves up with their own bombs, if they're trying to hit a target at a shallow depth, since their top speed is lower than that of an ocean-going escort.

Welcome to the party btw!
