2025.1 migration to 2025.2 broke block generation

Hello everyone. Recently, after 2025.2 release came out, I found a bug that no longer generates block classes in workspace I migrated from 2025.1. After gradle project was set up I tried to run client and got errors for every single block I have in my mod:
It turns out no classes were registered for blocks and block folder doesn't exist for them. When I tried to create a new workspace and create a block, everything was running perfectly.
My workspace:


Test workspace:


I have tried to create the block folder manually, recreating every block, fully reinstalling mcreator, regenerating the code and gradle project. Nothing worked. I don't want to create classes for blocks manually every time, so if you know how to fix this let me know!

@Klemen thats true, in 2025.2 1.21.4 every block from older versions es. 1.21.1 gives you tons of errors due to a change made by devs of neoforge between 1.21.1 and 1.21.4 i think

It should work fine. If you don't use plugins and see this error, please open a bug report on github, attach logs and your workspace

It worked for me.
It might be a bug in mcreator

You need to check it for the block to appear in the world. It's an option above the blocks that can replace it.
