you cant open iron doors with right click anymore when its locked with lwc, only left click. you were able to do this before 1.11
This is a known bug with 1.11 (after doing some searching I found out that other servers have this issue).
I discovered this bug yesterday after the server came back online & @ClarinetPhoenix told me to just left click (punch) the door for now since it is doing this. Also, whenever you right click the iron door, it's skipping a motion to where it's supposed to stay open but the goes back to the position it was in. That in my opinion is why it gives you two locked by you/user messages.
I'm just wondering here - did this work until right before 1.11? I'm asking because right-click stopped working for me multiple weeks (Maybe 1.5-2 months) ago, so I don't really see a difference between pre- and post-update behavior.
