During flight makes sense. The rest doesn't. I'd have to look at the source to be sure, but if I had to guess I'd say the goal was to exempt players flying in creative from the effects, and the rest was an unintended side effect. The effects are subtle enough within the confines of vanilla Mincraft gameplay that it's gone unnoticed.
Will there at least be a response to this?
Bumpity? I'm not sure why this was overlooked when the effects were introduced, but it'd be very nice to have it fixed. At least a response if no fix is planned.
Or perhaps allow me to join Mojang so I can help you guys fix it myself? 😉
This is clearly a bug as far as I'm concerned. Instead of having this get insta-nixed by the OPINIONS of the moderators, how about you leave this open so that MOJANG can look at it.
