I spend several hours today trying to fix the sound bug, which I had already fixed for TROM3 v1.81, but reappeared after CA's latest patches. After fixing the newly affected vanilla units I discovered that the bug now shifted to some of my custom made units, which weren't affected before! I had to scrap all changes and decided to put the mod on hold, which means I won't continue modding S2 until CA fixed thr sound bug. Sorry for that, but I am really pissed, and won't waste my time any longer.
