Hello!
I'm here again after quite some time since the last update. With a new major bug fixing related to the glass being moveable in the GUI's, which is not intended, and I'm sorry for this being a bug for quite some time.
Though somewhat luckily I guess is that it has only affected the 1.13.1-and-above version, so if you are not using that version there is not much of a worry. Though as I previously stated, I'm sorry for this issue not being fixed sooner, and if there are issues similar please report them to me.
And have a great day and continuos week
