Okay, this is the first time I see such an issue. I've been adding a script based unit trading. On one of my tests I noticed that one unit's selection box is now much bigger.
Selection Box Issue
I haven't messed with the collection of this unit, it is a slightly modified version of the Myth 2 version. Under Loathing the selection box is normal for the unit and an artifact that uses the same sequence. Run the game and both the unit and artifact have a huge selection box. I run one of the other maps with this same exact unit, and the box is normal.
The only thing I can think of that could have somehow been a factor was that I placed invisible units of this type from each team in the same one spot. Perhaps somehow it corrupted the unit to have a huge selection box. I'm still messing with it.
Selection Box Bug
selection box
since selection boxes can now be resized when checked flag... maybe that particular sequence always had a jacked selection box though it didnt matter since it didnt have the option to resize before.... maybe?
if one does not learn from the failings of the past they are likely to suffer its return.
