Physics problem with teleporters and high altitudes

I've sent in bug reports for this problem, but I thought I'd check here as well and see if anybody else has seen it happening.

I have a few teleporters set up on my land to go to sky platforms-- vendors, a skydive platform, etc. They're made from a freebie of Cubey's that I picked up somewhere. I also have a couple that a friend set up, made from a different basic TP. They've all worked great up until about a week ago.

All of a sudden none of them work anymore. When I click one to teleport, I go to the destination location and then continue rising up into the air. After a couple seconds I start flailing around as if I'm falling. I just keep rising and can't land at all, I have to teleport to get out of this.

I've noticed the same thing at high altitudes without even using a teleporter. I have a skybox at a higher altitude, and as an experiment, I flew up to it using a staff with a flight script. I used the standard pan-camera-in-and-sit trick to get in, and right away the same thing happened... went right into the 'falling' animation, couldn't land at all.

Has anybody else noticed this happening? Is it a problem with scripts, with altitude, etc.? Is there anything simple I can do to fix it? I've tried pulling a fresh copy of the teleporter out of inventory and setting it, but I get the same effect. I'm really at a loss to know what to do... if anybody has any suggestions, I'd appreciate it. Thanks!

I haven't seen that particular high-altitude teleport problem, but I've got one that occasionally bounces the teleportee off the (non physics-enabled) floor, and throws them tens of meters onto the neighbours' property. I think these might be related problems, but we'll see what the people who know have to say.

I've seen this bug before--Your buoyancy seems to be suddenly set to 0, and you float around aimlessly.

However, the bug I observed was not at high altitudes, only about 100m.

Uh... whoa that sounds wacked off. Ilianexsi, where exactly does this happen? I wanna experience this for myself.

Yeah, it's pretty bizarre.... it's on my land, Dunraven, at Moraine 150,68. I have a set of three teleporters on the ground, and it happens with all of them. Also with the teleporters on the sky platforms that are supposed to go back to the ground.
