1. Bug report: In Sector A9 Omerta, an enemy helicopter dropped off a team to attack my mercs which were training there. I went to the sector for the battle, it asked me to place my troops (makes no sense because they were already there). There was nowhere on the map perimeter to place them so I clicked "Spread". I received a Runtime Error Assertion Failure [Line 1144 file Map Edgepoints.cpp].
2. I have a save game just before. Can't upload due to less than 10 forum posts. Also have a screenshot. https: //www.dropbox.com/sh/tp3mga3hbrdi62d/AADU07i9hrVcas6P8VoRTHs3a?dl=0
3. On the save game, just advance time until the attack. Then go to the battle and click "Spread".
4. Running Windows 10, JA 2 1.13 build 8408 (12 Jun 2017)
5. No mods

In r8446 I fixed an annoying bug with this feature: when an enemy airdrop occurred in a sector that had mercs, you often got to a point where you entered the sector, where prompted to place your mercs... and then couldn't do so. This has been fixed (unless I missed yet another method to start battles).
