Is this normal for salem? I can go up or down jumping up the cliff. I made a gif but its 150mb :shock:

I don't remember being able to do it in the last world. If its intentional, its retarded.

See information about the "teleportation" bug. The server screws up and sends you half the correct information, but the next tiles are from the last area you were at or just the wrong location. There's some pretty funny screenshots about this floating around Bugs and the old screenshots thread.

The server does not correct itself though? I can literally just walk over it and continue on.

You can do one of two things: Port out (town or home, whichever) and back again and things should look like they are supposed to OR you can log out and back in.

It's a strange bug that pops up and is visual only. My understanding is that the server sees you in the correct location, but the client is displaying the wrong information. I've not experienced it personally. I'm not sure what the behavior is if you wander on.

I've no idea. Since it's pretty easily worked around, I don't think it has been a high priority to fix. It may be one of those odd bugs that is being hard to pin down for loftar, too.

I should have run a packet capture.

basically, the client doesn't correctly invalidate its map cache and never asks the server for information on those cuts. Since the height will probably differ wildly compared to where you teleported from, you'll get huge height differences. But the server handles all logic about cliffs / walking so the client simply displays the wrong things, while the server knows what's actually up. The only things the client shows wrong should be the terrain, though. Any 3D entities are sent/removed by the server without a client query, so these shouldn't linger or remain invisible.
