@Mistergreen:
I encountered a bug. When doing a test run of a amphibious assault I noticed that I was not allowed to retreat in the sea battle. If this is supposed to work I can provide a save file. Also this was game version 3.4 tripleA version 1.6.1.2
i just tested it and was able to successfully retreat from a sea battle, before the amphibious assault
please note that you can not retreat until the end of each combat round
and if there is no sea battle, you also can not retreat
and if your units did not come from another sea zone (ie: they started there and never moved) then they also would not be able to retreat
if what you have is still a bug, please send it to me, or give me a link, or upload here
