That doesn’t always work. I had an address that worked for 3 or 4 galaxies. But on the 5th it stopped working, and never worked again. The same portal address may not work in different galaxies.
@Mad-Hatter the galaxies are not clones of each other.
"According to game data manipulation, the procedural engine can generate up to 256 distinct-looking galaxies (using an 8=bit seed). It was originally believed that galaxies after the 256th would start looking like previously generated ones. However galaxy 257 Yilsrussimil Galaxy appears to be a new and unique galaxy like the previous 256. "
