On a flatland world in version 12w50a, when I opened to LAN it made the other people on the world get a screen saying "End of stream" when I would use a lever to dispense a firework out of a dispenser. I tested this multiple times to see if it was just a small error but it happened every time.

No it was not but was surrounded by oak wooden planks with glass above it
to stop the firework it was 4 blocks high but the firework never launched

Was the firework going through lava by chance?
