They are bats, but they have completely broken. I'll try to get them fixed.

sometimes i had trouble getting into the bandit cave

Lag is seemingly wreaking havoc and warping players. I don't think there's anything I can do about it, sorry :( Stefan said he's going to eventually change the way data is handled so lots of players in the same level don't cause lag.

Pumpkin lantern is bugged in the caves. Colour turns normal when "refreshing" the players gani. Ex; going in water.
Thought you would rather see it here, then making a new thread.

There is NO light when in the caves. What you see in the caves isn't the light of the lantern, but a hole in the darkness. I felt it best to disable the lights so players don't spam it and "create suns."

I died while I went up one of those circle stairs, when I came out in the new level I still had 1 Heart.

First time I got the rusty key, I held it up and the Npc was finished talking. It wasnt added to my inventory and I had to do the Fish Hold again.

Third is occuring to only some people. You cant hold your loot out. You can click at it x-times or change it. But you just can hold it out

This is sort of working as intended. It handles all the exchanges at the same time. If for whatever reason it fails to give you the key, you don't lose your fish and get stuck. It could be for whatever variety of reasons, maybe lag or such.

The railroad bridging across the river from Castle to Belle Island is layered on TOP of players :0

Yes. Graal's layering is pretty primitive. You can't define whether it draws over individual players, but players as a whole. So when you are riding on them it draws under, and otherwise it draws over.

There's no real way to fix this other than using attachplayertoobj, which is insanely laggy/glitchy.

I am getting bats on occasion, but not everywhere... I wish I could tell you the specific levels so as to help out ;)

They look awesome, btw.

Got warped just now into a random patch of ocean with an object that says "Touch me to return to land!"
Seemed to be when I went from one location to another while on the railroad...

I can no longer get on my draisine on tracks that are over water. I have to be on land to do it.

Not sure if its a glitch but ive seen others getting on the railroad while in water.

I'm sure dusty or rufus made it that way, it isnt really realistic.

Mounting on a draisine whilst in water isn't realistic, but rails supported only by a pillar of air(a.k.a. nothing) is. Right.... Tbh, mounting a draisine in water sounds perfectly realistic to me, think of it like climbing onto a raft after coming out of the water.

*Climbs up on the draisine* *Slips on rails* Okay, think of it this way. The rails in the water could be extended to the bottom of the water you never know, or it could be floating over the water.

Ok let's get back on track draisine guys.

There seems to be an issue with screen scrolling (drag to scroll) not functioning in much of the railroad tunnels/bandit tunnels. I dunno if that's intentional?

Also, the bats' initial shadows are intermittently appearing... or not.
