Major army decimating bug discovered!
When using Training Grounds, if you leave your units inside the exchange window and open town, hero window, clues or spellbook they disappear! (took the time to confirm this, check other windows players might open too. Might be a good idea to never ACTUALLY remove units from the army until an exchange is made in any format). plz fix.
Thankfully my last save wasn't too far back.
Looking forward to official release tomorrow.
