I doubt that.
The autostand feature is by dafault on (you can change it under options, gameplay) and the movement you describe here is exactly what autostand does.
The problem with the displayed TUs is, that it ignores the autostand option and calculates the TUs always as crouched movement.
ok the autostand TU visual is bugged... thats for sure, it sucks a little bid but it isnt a big deal to handle it ingame.
I have found another bug thats messed really up in some situations...
i dont know how to explain that cause it is a rare bug, i just saw it a few times:
I give my order to a soldier with 30TU (sniper) in walking mode,i just checked it would take 12TU for this turn... so i would have 18TU left for a precision shoot, but after he arrived he just got only 16TU left.... WTF WTF WTF where are my 2TU... i only can remember that he spotted a civilian in that turn. but there is no way to handle this really... after he spotted civilian he just get his action done, anyways if he spotted a fuck it wouldnt take any TU normally or im wrong? that is a instant death for some situations ingame.
if anyone could help me to fix that problem would be nice.
