Description

« Hide

There's actually two bugs in region crossings and the spammy messages you get from vehicles.

1. Most of those messages you get are actually false positives. Nothing happened, some code in the server is printing a message, then going "oh, that's a vehicle", and letting you go through.

2. Some of the time, usually with a full parcel, it's not checking whether the vehicle is a vehicle (vehicles are supposed to be counted against sim overhead, not the current parcel) and starting the return process, then abandoning it partway through.

The latter bug is what's causing you to be half-unseated while flying, while the plane flies on. I don't know precisely which order it's doing things in... either the sim has told the client that you're unseated but it's still associating you with the vehicle, or the sim has unseated you but hasn't notified the client or the vehicle. Either way the updates between the client and the vehicle and the sim are broken.

Either the client is still talking to the sim you were and that sim has handed you off to the next sim, or the other way around... I haven't been able to be sure which is the case but the effects are the same. You can't unsit because the sim it's talking to doesn't know you're there. You can't move because the client is sending control events to a vehicle that's not getting them. You fall forever because the client isn't getting updates from your sim.

The fix to both bugs is for the sim software to check for a vehicle earlier in the process, and not go down any of the code paths that lead to you getting these messages or unseating you.

There's a related problem that happens when you hit an actual ban line in a vehicle. There appears to be some code in the sim itself to automatically unseat you if your vehicle is found inside a parcel you don't have access to (this is unnecessary, since you can't use this as an exploit to let you into the parcel) and again it's following the "bad" code path that leads to the partial unsit.

Summary

Parcel restrictions inappropriately applied to vehicles on border crossings.

Vehicles crossing region borders aren't always treated as vehicles and can get incorrectly returned if the destination parcel is no-entry or parcel-full
