So I started a minecraft bedrock server for my friends. However, as we were going down the staircase, we started taking half a heart of damage. We didn't really mind it until it did 6 hearts of damage. Turns out that going downstairs without stopping actually kills you. However, the version of this server was on 1.16.201.06 while the current minecraft version is 1.16.201 is the bug happening because the server is ahead of the current version in minecraft?

Also note to mind that this not happen on singleplayer.
