Playing on 1.19.21 on PC on multiplayer Bedrock server.
I pillared up 210 blocks above my base (spawn point set on bed at base) using scaffolding. I then build a floor of concrete (210 blocks above base still). I then pillared up 30 blocks using scaffolding and went out by 5-6 blocks using scaffolding. When standing 30 blocks up and 5-6 blocks out on scaffolding, I started to take fall damage. Another player on the server confirmed that I was teleporting quickly to the floor I had created (210 blocks above base) and then back to where I was on the scaffolding (30 blocks down and then teleported 30 blocks back up). I could not visually see this happen, but I was taking fall damage multiple times. Once I left my scaffolding platform (the 5-6 scaffolding blocks), I ceased taking fall damage. I pillared up nearby (30 blocks above that same concrete floor) using netherrack, and I did not experience fall damage.
The server does have some occasional lag, and there was some lag in placing scaffolding every now and then. This occurred over a period of an hour and a half. The next day (in real life), I went to the same location where the scaffolding was that I had built in the previous play session, and I was still taking fall damage on those 5-6 scaffolding blocks.
