When attempting to view classes from external libraries, like std::string, documentation attempts to link you to external documentation (for std::string, the website it would link is supposed to be cpprefrence.com), however instead the documentation appends the external link to the documentation website, resulting in links like this:
https://docs.geode-sdk.org/en.cppreference.com/w/cpp/xstring/string
Clicking on the std::string return type on the following link can demonstrate this: https://docs.geode-sdk.org/classes/geode/ModItemUIEvent
Sorry if this is a docs-specific issue, I'm unsure how Flash and the docs website, however I'm going to just assume this is a backend flash thing otherwise
