Conquest overun book

[Droop21]

In this game, I conquer the Marianas. This forces 3 Japanese planes to rebase and crashes the game. I've uploaded the game at the last production (USSR).

I'll probably relaunch at end of turn phase to rebase theses planes

Here is RAW:

Now change the control of the conquered home country. Every one of
its hexes occupied by a land or aircraft unit (most combat factors if
more than one), or in the uncontested (by any other major power) ZoC
of a land unit, becomes controlled by that unit’s controlling major
power; unless already controlled by another major power on the same
side. All other hexes in the home country become controlled by the
conquering major power. All other territory the conquered major
power or minor country controls remains under its control.

So you shouldn't have to rebase those aircraft at all, since the hexes would remain under Japanese control during conquest. It's a bug (and a nasty one, too).

That means that there are 2 bugs: the conquest and the overrun bug

[Centuur]

That is a very remote possibility. My first impression is that this bug will disappear, the moment hex control is done correctly.
