[MODSDK] World crashing + game crashing on exit while tryint to load project from editor

WIle working on my project today i stepped on a issue that broke everything

I copied Assembler block with all of it.s files using "Create Partial Copy"

Then i went into file Assembler500_BlockModelDefinition.partialdef and on bottom i saw 2x Model Dummys set up to vanilla ones

Next i changed it to freshly copied ones but while doing that i realised i don;t need extra files so i pushed around 5 times "Undo" button in editor

After pushing Undo button i went lil bit too back so i pressed like 2 times "Redo" button to come back to moment before editing Assembler500_BlockModelDefinition.partialdef and then i deleted those unnecessary copied dummy files

At that moment i restarted the editor and when it came back online crazy amount of errors popped out then everything started crashing, after another restarts i got less and less errors which was weird because i did nothing until one left then In partialdefs for assembler and refinery file i changed those BreakableBlockDefinition to those from vanilla folder and all errors were gone. I tried to start the game and since then every time i tried to load a new world i got error message that world cannot be initialized and to check logs. When i tried exit the game every time it's crashing

When i created a new mod folder and copied folder blocks and folder system from my project it started working. I have no idea what is causing editor to freak out
