So I made this excavator and my server crashed when I R-clicked with the hammer. The wheel works but the machine is not working. So I went to the Forge cfg file and changed the "removeErroringTileEntities = false to true and it worked to R-click the machine but the problem is the machine is not working the block you R-click with the hammer is becoming a ghost block wich makes the Excavator, not functioning.

Here is an image of the excavator:

It would help if you actually provided us the crashlog. That Forge config option will literally just remove that Tile from the world, which - surprise - will obviously not make the excavator work.

Sorry for the late response, but yes. I am aware of the forge config but then my server is gonna crash if I don't enable it. Here is the crash log from the server:
crash-2021-09-07_20.15.52-server.txt

Did you change the size of mineral veins in the server config? Because you are getting a divide by zero for the size of the vein...

I didn't touch anything on the config besides enabling that forge thing I was talking about and what does that mean? and Do you know how to fix it? Thanks for the response btw.

Another issue I found is that I can't click on the recipe for HOP graphite dust so I'm unable to use the arc furnace to make the rods.

Why is it closed?

Because it's fixed for the next build. No ETA on that though.

Ok thank you
