I can't reproduce this on a build of the current development code on GNU/Linux with a Qt version of 5.18.8. What OS and release or PTB version are you getting it on?

HANG ON. What's with a custom exit line to a room with an id of -1? That shouldn't be possible as that means the destination room does not exist. Please select that line and delete it ASAP - no wonder things are going 💥❗

It looks like our validation in this instance needs to be tougher :)

[Balakay]

Oh.. Yeah - I see whats happening. I use the custom exit lines to point to rooms that the mapper can't recognize (because the exits are either present or not depending on attributes of a character. Rather than prevent that from happening - it would be beneficial to let a line just exist without any real "purpose" In this case the purpose is largely as a visual aide.

[Balakay]

Well.. thats not 100% true - the destination DOES exist, but as a special exit (and not a normal connected exit)

[Balakay]

it identifies the target destionation.. but isn't setting it in properties. Another couple images below for when i create the exit lines this way:

Oh! That is a bit naughty - I thought we didn't allow a "special" exit to have the same identifier as a "normal" exit - the problem is that the latter have preset keys for use in the containers that hold the details of custom exit lines and those containers are used for both special and normal exits!
