How much of the old mod would theoretically work in the EE? Is the only thing stopping it really the beginning? If so, could plugging Cad's fix into the old mod have a shot?
Cadmus's script is working quite well for a standalone mod. I had to modify it a bit to make it work for D:OS. Right now I've got what looks like a working version.
The old one wasn't actually that complicated by itself, neither is this one. It's just a matter of finding the exact right script and hoping nothing else breaks.
Like for example one thing I tried was teleporting the players using CharacterTeleportToTrigger. Well that outright breaks the party formation behavior. I have absolutely no idea why. But when I switched it to TeleportPartyToTrigger it works fine. It just looks a little janky.
