Ok, I know what happened, steven. You added (SHRes, no problem there), SG.wad and another wad, possibly FF. It turned out that when adding SG, MAP25 was added, as well as the TEXTURE2 lump, the one that contained Sea Gate's textures. But when adding FF afterwards, MAP13 was added, as well as Frog Forest's TEXTURE2. This replaced Sea Gate's, and it's textures. That's why they were gone. In this beta time, you can only add one wad (except for SHRes.wad) at a time.

I thought I fixed that in the goal ring! I made sure I'd replace the corresponding sprites in srb2.srb and in the characters' individual lump names. I'll check it out.
The water current can indeed be completed by Knuckles, with the help of the invincibility time. I did that before releasing. But the truth is that it may be next to impossible to have a Sonic 100% obligatory segment, seeing that Knuckles will eventually loose all rings for which to enjoy the invincibility time, if the path is large enough. And I just want to make a small road with a current, not a highway! If the players want to use Knuckles and waste their rings, instead of using Sonic, fine. It's of little importance.
And Tails can't pass all of Knuckles segment, you should of cleared that better. He can however skip the large gap. I also tried it before releasing. But I'm not sure if Tails' diagonal flight technique is really or technique or a glitch to be removed. So as for now, I think that I'll wait until further options. If you tried using spin-fly rather than diagonal-fly, then I need to remind that Tails won't be able to spin(dash) in the final.
