I have the same problem!

When the reports exceed 100 or so ... they disappear!

But only if you refresh the game.

After a while it becomes necessary to refresh the game because it slows down if you do not.

I too would like so much that the number of battlereports that can be stored in the walkie-talkie was unlimited, or at least in the order of the thousands.

Twice in less than a week my Tactical Reports have vanished. These are critical to how I play the game for future reference and planning. Has Plarium set a limit on reports that can be retained? If so can you reverse that so unlimited reports are shown?
