It’s pretty well explained in the script itself already, but basically I’m trying to build a door which can be opened via a command by a few ranks in a group.
I’ve done a few tests and found out that the problem is in this:
if msg == ("Open1") then
For some reason, it refuses to recognize it if I send a message like that. It just… doesn’t work. The script itself is in workspace, which shouldn’t be an issue.
The bug appends a carriage return (\r) to everything, so for now check if msg == "Open1\r" then
No, you don’t type it yourself. \r makes a carriage return, the bug is where Roblox appends it to the string.
Omg… It works!
Thank you so much for your help. 
Hopefully it gets patched in the future!
Oh no… We’ve ran into a new issue.
It doesn’t work in-game.
I tried everything: !Open1, Open1, Open1\r and !Open1\r but nothing seems to work/respond.
It’s still stuck at the same spot.
