Block place bug

Sometimes blocks can't be placed. they are vanished. It happned only to certain blocks. other blocks can be placed in that area. Can u fix this.

what happen when you join the game with vanilla game

Nothing happened just join like before and I started building. I just see some blocks appear in my build layer and vanish.

did the same thing like in your video and no issue for me

I have figured out what happening. Inventory mod that I had interfere with inventory optimization plugin in server that preventing fast item swap. Now It seems like fixed. it isn't happening anymore

We don’t have such a plugin, thread closed and moved from Bug Reports to the Community Help Forum.
