Information: On 8/2/2018 I was playing the semi-finals on The Undergames (which I bought three  days ago) with being Shale and challenging the Korvek, while I was building up my dungeon with defenses and training my units I have found that the Core Door said it can be closed but when I clicked on it, said Open still I was confused so I asked Discord and the QA told me to report the bug because its a tool-tip bug and not a open/close kind of bug.
ScreenShots have been captured with Lightshot.
None, since its a bug in the game and I cannot do anything to trouble shoot it
