Disappearing Engines

[nightwave]

I've been having a problem with my engines disappearing from the engine designer. I can design an engine family & variant just fine, but when I quit and reload the program there will be one whole family missing. I'm using the Open Beta version with mods from the Workshop, but it's only mods for the car designer section. I'm sorry I can't tell you more, but I'll pay more attention from here out. If I can recall properly, it's been both V6's and V8's - flat plane and crossplane.

Whole families disappearing? Hmm, definitely has nothing to do with the workshop items. Can you check if the family missing is in your Documents\My Games\Automation\Engines folder?

So, it didn't disappear when I loaded it up this time, but I did check the folder. The files for the missing engines were not in the Families folder, but the engines for the missing ones can still be found in the Variants folder. So the variants still exist, it's just that something is deleting the family files and the game thinks its not there anymore (as far as my knowledge goes).

Interesting! I'll ask Cas about what could be causing this.

So I did an experiment and it confirmed an idea I had when I woke up this morning: if there are two engines with the same family name, it overwrites the .lua of the older one with the newer one, leaving the variants behind with no family. I'm having the issue because I'm creating two families with the same name but different years, and I guess the game doesn't recognize that it needs to keep both families around and saves over the older one.

Thanks for that! This info makes it possible to solve the issue we'll fix it with the next patch.
