The "entity" word I think is wrongly typed in the subtitles "subtitles.enity.generic.explode", when the end gateway spawn.
"subtitles.enity.generic.explode""subtitles.enity.generic.explode"I think it should be:
"subtitles.entity.generic.explode""subtitles.entity.generic.explode"Steps to reproduce
1. Show Subtitles: ON;
2. Enter the following command:
/playsound minecraft:block.end_gateway.spawn block @a
3. Look at the subtitles.
When this actually is fixed depends on the next asset deployment!
