I'm confused.
I saved in front of the wormhole.
Set the Coordinates in the Trainer Info / Map to f.e. Latias (259, 1414, 0 , 3460).
Set the flags under Event Flags / Research for 1-15 and unset 3.
And I land in the dark.
If i do the same and set the X,Y and Z Coords undr BlockData / Situation, I spawn in the right place, but it's only normal Pokemon and nnot the legendary.
