Why does it say Dimension id for 0 does not exist?

Jun 21, 2019
Ok so i have my own singleplayer modpack for my modded survival series on youtube called rulecraft the whole thing was running smoothley for 4 years until i tried loading in my world with 2 new mods Many systems and space advanced the game decided to take a dump and crash on me saying the dimension for the overworld does not exist and this crash has happened before but the people on MC forum blamed it on vanilla i think this is a galacticraft issue.
Since the spoiler bar doesnt exist here is the crash report log reason i find this strange becuase its been working for 4 years perfectly it doesnt go past this many characters and this is the log

I'm not sure how you have come to the conclusion that it's a GC issue. You added 2 mods that were not GC and your game crashes, so it's a GC issue how? Plane logic dictates that it's one of the two mods you just added. It would be a bit more helpful if you could post your entire log file on pastenbin.com (it's free) and provide a link to it and I'll try to help you. Thanks

Galacticraft registers the overworld ID to 0 so yes its a GC issue
# Dimension ID for the Moon

# Dimension ID for the Overworld (as seen in the Celestial Map)

# WorldProvider ID for Overworld Space Stations (advanced: do not change unless you have conflicts)

# WorldProvider ID for Static Space Stations (advanced: do not change unless you have conflicts)
