So what I’ve done here is start a local server with 3 players (as far as I can tell, this works with any number. I tried 8 but the recording was too laggy). All I have is a single part in the world as the baseplate. Upon setting CanCollide to false, the first player falls through a bit, and then sits on the baseplate.
This reproduces every time on Studio. I don’t know what it’s like online. (That’s why this isn’t in Client or Studio bugs)
In 8 player server tests, SOME of the players fell through. Most didn’t. As you can see in the video, the baseplate slows them down a little, and when they start falling from 0 velocity, the baseplate catches them. When they have just spawned, they always fall through.
Not a very critical bug, but I noticed it and it’s definitely a bug.
