You know how some enemies stop and wait for a short time before firing their weapons? The wait time used to be constant, but now it's random, meaning these enemies can fire much sooner than before, sometimes almost immediately after stopping. Sometimes they don't even fire before moving again. This seems to be most noticeable with fast enemies, such as Stalfos 3 and Octorok (Magic).
The test quest was made in build 1296 and this doesn't appear to happen in that build.
