When I try to place chisel blocks with FakePlayers(With a turtle from CC, a Drawbridge or a building wand), the block is a ghost block for the client.

Example
This is how the door should look like(Made with drawbridges)

This is the door when it's closed with the drawbridges.

I don't know if it's a chisel problem. Some other blocks also have these bugs(Applied energistics 2 as example).
But I hope you can help me or fix this.

+1. Been getting the same issue with other fake players, specifically builders wands and effortless building.
Also to add on, I've been getting the issues in 1.16.5

I found a solution

You can install connectivity on the server to fix this problem
