I was playing the Royal Jelly Boss Battle mission with some friends and we had just finished the battle and proceeded into the elevator, firstly the elevator icon should have been a house that ment that the mission was over, instead it showed the boss icon for the royal jelly. we got in the elevator and everything was normal just instead of it letting use go back to haven it said to advance to the next level, i pressed it and it took me back to the beginning of the royal jelly boss room, just there were no monster it was like the battle was finished already so we went back to the elevator but the bit you stand on was missing and if you stand in that area the whole level dissapears and your stood in the elevator. (I have screenshots on my steam profile because i dont know how to put them on here.)
I just wanted to make this post to tell people about this "Bug" because it dosent let you finish the mission, we had to leave without finishing which ment that we had not compleated the level and didnt get the mission reward.
