May I say something ryenSaotome. You need to fix some bug on the squad's captain they getting dmg even when the enemies are far away when the end turn happening and how I get all my save data again? My lvl there is 90+ and all the event item I got vanished when I installed the new version hehe
I'm not aware of a bug that causes enemies in the vanguard battles to attack over long distances. Can you describe it more detailed? Is the problem on every map? Is it by specific enemies? Have you done something in particular before it happens? Are the enemies over 3 tiles away? Have you loaded an auto-save or done anything else besides playing the battle normally?
How did you lose your saves? If you downloaded a new full game version, you need to copy&paste the entire content of the www/save folder, including the global file, or the game won't recognize your saves.
Do you, by chance, mean the "Bonus Battle 2" which at the start of the fights gives you a message which says:
"Special map feature:
The mage in the far east will deal 5 damage with a long distance fire spell to a random vanguard squad until he is defeated."?
If that is the battle you talk about, then it an intended feature, not a bug.
