When you occupy oasis or a fort your troops vanish, not there to callback and draw from them gone from city. This effects many players. My alliance leader lost whole army, 20k arch to a oasis and almost 30k cavs to a fort.
Please return all players troops who lost armies and fix glitch ASAP.
Since i cannot take oasis over risk of loosing army and inactives are getting cleaned out quick i and many other on server 92 are coming to the conclusion the only way to feed our armies is now to start farming actives, its going to get out of control very fast with everyone fighting for crop because no one can take oasis to feed their army.
