Entity is not a known factory.
Factorissimo get_factory_by_entity returns nil.
I can not initialize smart linked chests.

You don't need to report this. I apologize, but there is nothing I can do.
The cause lies outside this mod.
May be removing some other mods could help.

Using Factorissimo 3 by notnotmelon, placing a factory results in this error, both in any game and in the map editor.
I have only used the mods Factorissimo and Smart Linked Chests, so I am certain that the issue is not caused by other mods.
Additionally, I tested the official Space Age DLC and found that the error does not occur when the DLC is disabled, at which point the Smart Linked Chests mod appears to function normally.

Interesting thing. thanks for investigating this.
but unfortunately there is nothing i can do, the error is not in my mod. as i have already written.
that's why i intercepted a crash and replaced it with a warning that you could continue playing.

I will test this again together with the Factorissimo author to see if we can find a solution.

Hi, did the factorissimo author fix it?

unfortunately not yet

Hi!
It appears there won't be an easy solution any time soon.

At the moment everything appears to be working, but at any placement of a factory there is a bug report.
If one understands that this can cause damage to the safe file, can you please add a setting to ignore this error?

chest are not working properly if this error occurs. i need the factory data to calculate distance and other things
I only catch the error so that no one loses their current progress,

should be work now

The issue is no longer present now, thank you very much!
