Happened when I tried to load AAI Industries. Apparently advanced circuits have duped and either the mods or the game can't keep them separate.

Failed to load mods: Error while running setup for recipe prototype "ufo-electrodynamic-fragmentation-device" (recipe): Duplicate item ingredients are not allowed (advanced-circuit exists 2 or more times).

Mod version 1.0.6 if that's important. And it only mentions U.F.O as the mods to be disabled, no others.

Could you either post the complete list of the mod's you're using or share the save where the error occurs? Had a similar issue 2 days ago with a different modpack. May be there's a chance to see some similarities.

P.S.: Would prefer the shared save 😉

Not a modpack, just a collection of random mods I've been slowly growing. It only errored when I loaded a bunch of AAI mods. I think the mod that caused it was AAI Industry itself, since it was the only one to cause the error. All other mods work perfectly fine.

The addition of AAI Industry to the above mod list causes a crash on startup.

Fortunately I do not need to probe each of your mods – AAI Industry is obviously the player who commits the foul 😆. As soon as I add this to my mod list, the error occurs.

To quote Archimedes – Eureka.

AAI Industry changes the recipe of the assembly-machine3, which is the template for my ufo-electrodynamic-fragmentation-device and adds advanced-circuit (and other items) to the recipe of assembly-machine3. And my code (currently) is somewhat too simple and adds advanced-circuit a 2nd time . I will change that and make the logic in my code more resilient for such changes.

V 1.0.7 with a fix for that nasty bug is online.

Thanks

After updating, platform thrusters no longer accept fuel and oxidizer. Before updating, the thrusters were perfectly fine, but post-update, the thrusters just break completely. Re-placing them does nothing.

Hhm - U.F.O. doesn't deal with thrusters, fuel or oxidizer. So what make you think that there is a relationship?

Hover the mouse cursor over of the thrusters or look for the thruster entities in factoriopedia. There you can see which mod (if any) has modified the thrusters. And I would be REALLY surprised, if you would see there U.F.O.

I downgraded the mod, but that didn't fix the issue, so that's ruled out. I would assume it's one of the AAI mods I loaded recently. Going through each of them now to see which one was causing the issue, starting with Programmable Vehicles

Did you look – as I proposed – for mods altering the thrusters? That should be much faster than switching mods on/off 😉 to get an idea what's going on ...

The only mod I know of that alters thrusters in any way is visually, Disco Thrusters, and that's been working perfectly fine since I installed it. I'm guessing it may be Smooth Platform Walls, as I don't know how it would smooth out the walls outside of completely removing the space tiles directly touching the platform tiles. Although, it shouldn't just make the thrusters stop accepting fluids since they should accept fuel and oxidizer regardless of operational conditions.

Survey says: no

Just read your suggestion. I sometimes have a Redditor's reading comprehension. I will check now.

😆

Alongside Disco Thrusters and Space Age, the only other mod that has modified the thrusters in any way (also visually) is Factorio HD Age: Space Age - Logistics.
