When trying to launch Factorio with your mod enabled I get this error:

Failed to load mods: gacha/prototypes/setValue.lua:61: stack overflow
stack traceback:
gacha/prototypes/setValue.lua:61: in function 'es_get_price_loop'
gacha/prototypes/setValue.lua:61: in function 'es_get_price_loop'
gacha/prototypes/setValue.lua:61: in function 'es_get_price_loop'

It goes on like that forever.

Only vanilla and space-age have been confirmed to work.
It seems to be due to another mod.
I think there is a mod that includes a circular recipe, so please tell me which mod to install.

I think it would be:
Omnia's - Stone -> Crushed Stone -> Stone
Renai Transportation's - Iron Chest -> Open Chest -> Iron Chest
I'll check to make sure there are no other ones.

Okay after doing some more thorough checks:
The Omnia/Muluna stone thing is no longer infinite, so that one shouldn't be an issue.
Renai Transportation still has the "Iron Chest -> Open Chest -> Iron Chest" recipe
Metal & Stars has "Rocket/Nuclear/Dark matter Fuel -> Liquid Rocket/Nuclear/Dark matter Fuel -> Rocket/Nuclear/Dark matter Fuel" with the recipes being named "Empty liquid x fuel" and "Canister liquid X fuel"
These are the only recipes I've found, so far.
There might be more, so I'll keep lookout, but I think these might be it.

Thank you for looking into this.
Please be patient as we look into how to fix this.

I have released version 0.2.1, which incorporates a countermeasure against infinite loops.

Thanks a lot. I'll try it out later today, if I have time!

Well, here we are again:

Sorry, I didn't anticipate the case where the recipe result does not include the amount.
0.2.2 has been released. Please check it out.

I'm updating as we speak. I'll let you know if it works or not.

I'm sorry I'm just stupid.
0.2.4 has been released. Please check it out.

I'll check it out immediately

I'm sorry I'm just stupid.
0.2.4 has been released. Please check it out.

And don't be too hard on yourself. Modding is hard. Especially when it comes to cross-mod compatibility issues. Thank you for all your work

Thank you for your support, it's encouraging.
However, this may not be an effective solution at this time.
0.2.5 has been released. Please check it out.

Failed to load mods: Error in assignID: item-subgroup with name 'coin_g-pipesa' does not exist.

Mods to be disabled:

We're getting there - 1 error at a time :)

I think this might not actually be on you. I need to check something

There is an error in the subgroup I added in my mod, so there is a problem with this mod. I'm sorry.
I hope this is another step forward.
0.2.6 has been released. Please check it out.

I seem to be able to load in, though I was on a different mod list for testing purposes. I'll be able to tell you if it worked in around 5 mins

I hope for good results.

I loaded in successfully! And for some reason I loaded in way faster than usual!
(I'm stupid, the other mod list didn't have gacha in yet...)

I'm glad the errors are gone.
I hope you enjoy the content.

As much as it pains me, I must sadly bash your hopes:

I had realized that my real mod list didn't actually have Gacha in it, so I had to load again. This, sadly, resulted in another error. I attached the log this time, since it might help more than the minimal info the actual error gave, though I will attach the error as well:

I understand the cause, but I'm still wondering how to solve it.
It takes time.

No need to rush. Take your time with it. I'll still be around to test it, even if it takes longer.

The icon size settings have been revised.
0.2.7 has been released. Please check it out.

I have successfully loaded in. You did it!
Thank you for all your work <3

After playing around with it I can report that I have not encountered any other issues so far.

Thank you for putting up with this long project.
Please let me know if you have any other questions.
