The lighting was summoned with a /summon command.
There are no crashes when a mob is riding a minecart or another mob.
When re-entering the game, the boat is gone, and the entity is unaffected (doesn't convert, or take damage).
Tested on [villagers/pigs/mooshrooms/llamas/players] riding [boats/minecarts/llamas/llamas with one health].

Crash report:
```
The game crashed whilst ticking entity
Error: java.lang.NullPointerException: Cannot invoke "deu.j()" because "$$0" is null
