I downloaded the latest version 1.16.2-1.0.2, I have 36 other mods installed, not sure if they are incompatible but once I removed "harvest" I was able to place the crafting table down. I haven't tried to re-install it. I'm on forge 33.0.22

Do you have the crashlog? Without it I cant really check :)

Sorry about that, I assumed I had uploaded it. Created a new crash log about now with no mods other than forge installed.

I notice it happens whenever I right click grass. Not necessarily placing down crafting table.

I cant replicate the issue, at least with forge 33.0.57. So I hope it will be fixed for you with this.

Using your 1.0.2 file, I still had the same crash even when using forge 33.0.57 and 33.0.61 but when I used your updated 1.0.3 harvest file, it all seemed to work flawlessly. Thanks
