Not true.
I have used the mod in the past, and many other game mods found on F95.
I was playing an early stage of the game after having to reinstall windows, and deleted all of my save files, so old saves was not an issue.
Since I was playing again from the very beginning, there should have been no crash on day 2 of the game, unless something was changed that affected day 2, that disagreed with the tweak mod settings and caused a crash in those rooms.
I can understand the mod not working for events found in version 16, but those events were old and long established in game time, unless Runey changed something recently that changed something about those events on day 2, that the tweak mod cannot handle.
Which is why I am telling the person who has been working on the mod, so that he can look into it.
If I am wrong, then my apologies, but game developers and mods can't fix potential errors, if no one speaks up.
