NOTE: This plugin only works with Minecraft Forge 47.4.x
Although we no longer support or encourage the use of 1.20.1, we still want you to update to newer versions of MCreator. For the time being, we try to bring feature parity to the plugin, but only to the extent that it is technically feasible.
This generator is a legacy compatibility plugin.

We also need to be sure of various other things—for instance, that you'll tell us if you know that your code infringes on other people's patents. You don't have to sign the CLA until after you've submitted your code for review and we approved it, but you must do it before we can put your code into our codebase.

Comments
Ok this is the pastebin link

I also noticed that I was able to add a living entity in the same version in another, empty workspace without any problems, but although the codes etc. are the same, it is not working in my original project.
Bug where "set text in textfield" doesn't work. Tried to make a autofill feature upon opening a gui and with the text synchronizer plugin it worked. MCreator 2025.2 says it has synchronized text but it does not work, at least for this generator, I have no clue about other generators.
Found an unusual issue
https://pastebin.com/d0in7Vjq
Creating a mod using this generator on 2025.2 leads to a problem where it is missing the .<init>() in the compiled version.
I've reinstalled MCreator several times, and this plugin several times to no avail unfortunately. And it happens with *every* mod I attempt to put onto 1.20.1 using this plugin. It used to work too which has me a little perplexed.
I need to figure out the cause as 1.20.1 is still by far the most popular version for my mods.
I tried adding a living entity to my mod, but whenever I tried to run the client, it crashed and gave the following error:
[01:18:47] [Render thread/ERROR] [ne.mi.fm.ja.FMLModContainer/]: Exception caught during firing event: Registry Object not present:
I couldn't figure out what the problem was because, similarly, I didn't encounter any errors in Mcreator 2023.4 with the same code in the same Java class.
