I had an issue where my enemy explosions were appearing in the game view but not doing anything.
This was because I had left them disabled when I re-prefabbed them.
In Ben’s video at around the 2:06-2:08 mark there is a green arrow pointing at the checkbox to re-enable them.
I ended up missing this and having a difficult time figuring out why as there were no technical errors being logged to the console.
Just FYI so people don’t do what I do
