Hello again.
I am unable to duplicate this problem. I too have turned off all other plugins, except for the three listed in your report, and the scene is still accessible via the menu command in the main menu manager, and the crash you report does not happen.
To help track down the cause of the error, it is best to eliminate as many possible compatibility issues as we can. I use more or less the same demo project I have uploaded here for testing, and it appears that, at least on my end, the problem doesn't happen from within that project.
If I can get you to confirm on your end that the demo does not crash when you import the required yanfly plugins into it, and turn the main menu manager plugin on, we can at least confirm that the baseline works.
If it turns out, as I suspect that the demo is no affected by this bug, but your project is, there are still a couple of other things that might cause the issue:
- You might be using a different version of the main menu manager plugin. The version I'm using in the demo project is v1.02, I'm actually not sure if there is a newer version available, but if there is, it might be interfering somehow.
- Your project might belong to an older version of RMMV, with outdated core js files, which might be causing an issue. The demo is made with all the core files from v1.6.2. Note that even if your RMMV installation is from version 1.6.2 (via steam or whatever) the core files in your projects do not update automatically when the application updates.
- You might be using an old save file to test this project, that was created before you installed the crafting system plugin, and the plugin parameters for the crafting system plugin are not initialized correctly in your older save, resulting in the main menu manager checking for values such as the unlocked/hide options being undefined, causing crashes.
I feel like the third option is the most likely, as commandCrafting is clearly defined on line 3879 in my plugin, but is being called as undefined in your error message. Try starting a new save file and see if the error is still there.
Thanks.
