[Discussion] Strange Error on my Game

I've been trying to update my game from v17 to v19. I've been uploading all the scripts, so I don't know if that has something to do with it, but it gave me this strange error.


It's in the GameData section of the scripts, but I'm not even sure what this error is. I didn't even touch this GameData script. I think the line that it's trying to get me to fix is in line 62 and 221. 62 simply says: const_set(:DATA, load_data("Data/#{self::DATA_FILENAME}"))
Before that, in line 61, it's: def load
Seems like it has something to do with what it says, but I don't know what to fix.
Then in line 221: Species.load
I really don't understand what it's trying to get me to fix here. But that's just the first few. There's also errors for StartGame and Main. If I could get some help, that would be great, thanks.

That's not what I asked, but I have a feeling you know that and did that on purpose.

The error is in line 62 of section 101. The rest is there because the method that was defined in that line was called in said lines.

Anyways, could I have some info on what you changed? Thanks in advance.

What I did is just go to the project file in the folder for the game, and as SOON as the window pops up, you hit the CTRL button. Then you'll see that it's starting to load something, and it will most likely fix the error.
