I am playing a battle as riftborn against AI riftborn at turn 180.  My system is deep within other players influence area.  We are at war.

I have a fleet of 13 ships command points 20, AI has 3 ships, one being a carrier.

going to advanced battle play I notice that all my ships have been placed into the centre flotilla box, while the other two flotilla boxes are greyed out, not allowing me to place some of my fleet into these boxes.  I want split my fleet up into three flotillas.  I hit the play button and battle starts.  All seems well, I destroy the enemy carrier than all ships freeze, showing no movement yet ice fields are moving and battle duration is continuing.  After battle report says I have lost all my ships and the battle.  Thought this must be a mistake as no way can 13 against three result in such a grave defeat.

I then reloaded autosaves and tested this out to find that in some cases the flotillas could be effectively split and when this was allowed I won every time on same battle settings.  Some times only one flotilla slot was greyed out, sometimes all where available, and sometimes only one was available.  I used all three autosave options with different results.  Not sure if I am missing some thing obvious.  

Also while on the subject of autosaves, sometimes they do not load forcing me to use task manager to exit program and restart game.  Screen says loading but it just sits there.  Also exiting to desktop sometimes freezes game menu screen forcing a task manager exit, this is less common but still happens more than it should.

Great game so far.

Continued to play but have encountered many problems with this node.  Fleets in orbit not being able to send ships back to hanger, clicking on fleets freezes selection.  Forced to click onto another system to free it up.  I suspect that this node has become corrupt, wondering if influence is effecting this system as rest of game is ok.  My playstyle is to hang onto a system that is well within other empires domain.  Every game I have played has resulted in node problem after 150 turns.  Ask if other play testers have had same problems with nodes.

Just gave up on this game at turn 210, consistent battle errors on same node.

I have several saves that led up to this problem if they are helpful.  Have sent some save for you to look at.test 6.zip

the node in question is WARDEN.
