Here are a few bugs that existed for a very long time:

Red Lanmola and Bats are using the wrong tiles in New Enemy Tiles. Red Lanmolas use Blue Lanmola tiles while the Bats use the Keese Tribble tiles. Originated when New Enemy Tiles were first in the beta.

When you defeat some enemies with No Flashing Death on, the flash still occurs. Go ahead in New182test Quest with No Flashing Death on and beat a Blue Wizzrobe. The flash still occurs, even though you have the rule on. Originated in the 1.90 days of Zelda Classic.

I reported these bugs like a million times before a new beta would come out. I hope these bugs are gone next beta.
