So I fixed the import / edit map coming with broken scripts.

However I could not replicate with the steps above the map override issue :^(

I appreciate how frustrating it must be and I apologize for that, however I will need replication steps to be able to pinpoint the exact issue. If I get time I might hunt how to replicate but until then if anyone have a reliable way to produce this, I'm all hear.

PickList was indeed borked for World object lists, this will be fixed next patch = )

Ah ! The manual event trigger can accept string objects, not number/decimal. But you can construct a random number into a string as I mentioned in another of your tickets I believe. And then use it in there = )

Hope that helps, if not let me know and I'll assist further
