Don't know if this was covered or not, or if it's a problem or just something that has to be like this, but spawn blocks only work for the highest value spawn placed on the screen. As in, if you had the A, B, and C triggers on the same screen and the A, B, and C spawn on the same screen, only the C spawn block would work. And if only A and B are on the same screen, only the B spawn block would work. Otherwise, the sprites spawn at the designated spot in the script.
