Issue
When both Inventorio and the Curios API mod are installed in Minecraft 1.20.1, the game crashes during the loading process. This incompatibility prevents players from using these mods together, disrupting gameplay.

Details
Crash Occurrence: The crash happens during the common_setup event phase as the game initializes with both mods active.
Environment:
Minecraft Version: 1.20.1
Inventorio Version: inventorio-mc1.20.1-forge-v1.10.3.jar
Curios API Version: curios-forge-5.12.1+1.20.1.jar
Loader: Forge - 47.322

Could the Inventorio developers look into this incompatibility with Curios and work toward a fix? A solution would greatly enhance the experience for players using both mods. I’m happy to provide more details—like the exact crash log or testing with different versions—if it helps resolve this issue.

Additional Notes
This issue affects the community of players who enjoy both Inventorio’s inventory enhancements and Curios’ equipment slot features. Fixing this would make the mods more compatible and improve gameplay for many users. Thanks for your support!

you can downgrade curios api to 5.10.0 until the devs have a fix
im from another country so my english may be bad

I too have this problem. I drafted a report, here is most of it if it helps.

I have figured out the hard way through Extensive Testing that Inventorio is hard imcompatible with Curios. The engine is Minecraft Java 1.20.1 Forge 47.3.0. I have provided my crash report. To be clear, the only mods loaded are: [Cloth Config, Curios, Inventorio, KotlinForForge]. No config files or ingame options were changed for either mod or the 2 dependencies. I have yet to try older versions of either mod.

As a mod author myself, I think it is a problem with both mods changing the inventory GUI. Is your GUI not extending the vanilla one perhaps? It also might need alternate code specialized for Curios, I don't know. I did not look at the code as I felt it made more sense to report this.
