In GHZ Act 2, Go down the bottom path near the exit, instead of going into the tunnel to take the exit. There is a Neutron that appears. Something weird happens here. If you let him appear without going to the left of him, he will act normal. If you quickly run past him though, he will change colors to the green Neutron before deploying... otherwise retaining the same old behavior. I have not seen this with any other Neutron in any other GHZ act... I got a screengrab and savestate stored if you cannot replicate it.
There is still a bug with the lightning shield in Labyrinth Zone boss, though I have a good hunch as to what the problem is. I had all 3 characters, and was Sonic. Tails was above water with me, and Knuckles was underwater below. Everyone had water shields, except Sonic. I got the lightning shield, and Sonic got the lightning shield, while Tails was left with nothing. If you cant replicate this, I can get the savestate to you, along with a screen grab. I was extra careful to store this stuff this time.
I'll check everything I found in the new release before posting anymore. AND I tried to replicate the bug with the ALL Sol Emeralds screen. No such luck, though I had all 3 characters this time, and was on a different build. I'll keep trying to replicate it, but it turns out I accidentally had overwritten the previous savestate that had the bug.
