Well, here is how it comes.
Create a completely new map, maybe also after restarting the map editor.
Then select the Holocube, DO NOT PLACE IT, but instantly try to create a new conversation entry. The Box will say the Message is from "UKNONWN" , whyever.
Well, if you now put a message in this box, (now put the cube somewhere), deselect it and reselect the cube, it dissapeared. Just gone. And that was it.
Just a minor bug, still it may be surprising when building a new map ^^
Most of the time I normally place the holocube before i start making a conversation. I see it as a bug but i think it isn't that important.
Was it not one of the two of you that initially reported this in Beta?
yes i reported this on beta actually twice.
Just thought the non-betas should also know about it ^^
Yes, indeed. Good idea.
