Disappearing Abe?
 

Doing as I do normally, I was playing Abe's Exoddus yesterday on my hunt for this elusive missing mudokon that I always seem to miss out. So I am in the Slig Barracks ender, posessed Dripik, had him explode, just had to get out past the greeters...misjudged the jump, got zapped. All fine and normal...except I didn't die, and somehow got zapped twice. Still alive as Abe...but Abe wasn't there. He was a shadow on the ground, still walking around and everything, but there was no Abe, he'd completely disappeared. Never seen anything like that before. Anyone have any clue about this? It is the playstation version and I did not have he invincibility cheat running, so I should have died from that greeter zap...

Did you continue to get zapped while walking about? If so and you die, Abe might respawn as the fully visible avatar you need. Or does Abe regain his opacity once you take him through a door?

Years ago I played with the invulnerability cheat, and had fun messing with the greeters. Often I would find that this would lock Abe's sprite into some shade of disintegration, sometimes appearing as a blue ghost of varying brightness, sometimes black and transparent, sometimes not there at all, identified only by his shadow and foot dust. It was be reset when I died, or changed when the greeters shocked me again. Going to new regions reset his sprite also.

It's just a glitch. Do what was stated in the above posts and you should be fine.

I ended up saving it with the sprite not there and when reloading it he came back to normal, phew.
I only got shocked the twice by one greeter in quick sucession, didn't get shocked again afterward

Oh, I'd understand it if I had the invulnerability cheat on, but I didn't, that is the thing. I should have died. Going to a new region didn't reset it for me though, I ended up going from the greeters place back to feeco afterward and I was still not there in feeco

Woah! You've had the disappearing glitch too?

I also got it in Slig Barracks in Block 4, part 2.

Whenever I tried to throw a grenade,

1. The Flying Slig on the screen disappeared and reappeared black and pixelated in place of Abe, who also disappeared.
2. When Abe disappears, I lose all control of him, so I can't stop the grenade from blowing me up. If he is crouching, however, the grenade doesn't beep at all and Abe occasionally explodes without warning.
3. After I leave Block 4, whenever I try to throw a grenade, the game freezes for a few seconds.

EDIT: This problem remains in my save file until I leave Slig Barracks. If you do Block 4 before Blocks 1, 2, and 3 and this glitch occurs, it becomes impossible to progress.
It was extremely funny though.
