So im a long way into my Spartan campaign and ive run into this before but it never made me as mad as it just did. I am fighting the Celtic Confederation and the Advernii in the north and they landed on one of my coastal settlements. So instead of losing 1000 guys needlessly I met their 5000+ Army on the field of battle!!!!

My 1000 guys fought like gods and actually I won the battle! Well except for the fact that one Celtic slinger unit wont disembark and route properly..... What can I do to fix this?
