So, I just updated today to 6M62 (after a long hiatus from Inform 7 and interactive fiction in general) and it works great, as far as I could tell. However, I needed a conversation extension for a new project (well, an old project that had little work on it that I returned to) and I decided that menu-based was the way I wanted to go with it. Long story short, I downloaded Mark Tilford’s Simple Chat and placed it in my extensions. For whatever reason, without even including the extension within my code (you know, “Include Simple Chat by Mark Tilford.”) Inform 7 decided it could no longer save my project. No matter what I did — restarting Inform 7, deleting Simple Chat from my extensions folder, etc. — Inform 7 could not save my project. It took a fresh install to allow me to save again. Just to be thorough, I added Simple Chat to extensions again several times, and each time it broke Inform (I tried maybe three or four times).
I guess this is sort of a PSA. It may or may not happen to you, but before putting it in your extensions I would save whatever projects you have open.
This is also sort of me asking if there are any other good menu-based conversation extensions out there.
(NOTE: There was no crash log or anything like that, just a window popping up when I tried to save saying “Failed to save project.” I also know that Simple Chat was made to work with 6G60, but that version was released almost 6 years ago, so I assume that if it broke any of the versions between then and now, someone would have said something… Maybe someone has and I just haven’t look hard enough.)
