Well, weird thing is it happened to Val as well, right?
Have you tried using the first blue/greenish teleport after the first room?
Cause this is what gets me there, the first room with enemies seems to be working fine for me atm.
Some people just remade a Desert game because they got stuck in a room with a closed door, despite it being shown green on the radar.
It's weird, just saying.
That was the result of me trying to get around a QEdit oddity.
QEdit doesn't know how to read the episode # inside of a quest binary file (seriously, there's actually a dedicated byte for this) and relies on the "set_episode" opcode's existance to know which Episode you're working with.
The .bin files for Pioneer 2 (Episode 4) and the Lab don't have set_episode, so QEdit always shows them as Episode 1. I added the set_episode opcode while editing Pioneer 2 and the Lab so I could see the correct layouts for them.
I didn't think it'd cause a problem with the episodes and didn't with my quick testing, but, of course, it did.
So I just have to remember to add the opcode when working on future edits of Pioneer 2 and the Lab and to delete it when I'm done.
If you're editing the default quest, import the enemy and object files when Qedit is already showing the correct episode, then export them again when you're done (without having a script at all, or using a script from some other random quest that's in the right episode). If you're editing the default script, ignore the map completely.
