I've done a lot of work on both and consider them both stable and very usable.
Not to start something but it seems dishonest to say "you" have been doing a lot of work when TitanAPI was obviously made by taking TethysAPI (without giving any credit to Arklon or even acknowledging that you used it as a base) and feeding it through an LLM.
Regardless of its origins, I like the attempt to add more robust error handling so the game doesn't crash at the drop of a hat, but a quick glance through it reveals some glaring inaccuracies and usability issues that make it ill-suited for non-trivial mission development.
