i've had that problem with other games, it turned out it was the unren console script that was causing it, they have some hardcore no console shit in the code, why i dunno. some ppl are weird about cheating in games.
Unren console does no such thing. There are, in fact, duplicated labels across the files, when there should be a redirect of some sort from the default label. I had to manual reconcile a bunch of things when I played .06. I don't remember exactly what I changed but it was a lot. Sometimes leaving files unextracted prevents duplicate label reads if you have multiple RPAs with some sort of version patching, but I don't know enough about that to say anything about how it works. But if you have duplicate labels in extracted .rpys, you have to change/reconcile them or you will have issues.
EDIT: To provide an example of what I'm talking about, this is a redirect from "The Web We Weave":
That redirects the labels from the unpatched game to the patched versions of the labels. There are other methods like single line redirects, or the one this game uses with persistent variables and string variables for different versions of certain lines. The issue crops up in the patches where there are just labels that use the exact same name as the label in the default game files.
EDIT 2: I've had no issues with the console in this game, nor did I see any of the shenanigans some devs like to pull if you activate developer mode or the console. IDK what issues that person could have besides maybe some leftover patch files from a previous version of the game if they didn't just extract to a new folder and move their saves from the old one and instead did an overwrite (never recommended unless there's a foolproof update patch) in the old folder.
