Was able to retreat to a just captured territory

@Panther said in Was able to retreat to a just captured territory:

But: When I added the bomber’s attack, the bomber flies over (pre-battle) East Poland. By this action it seems to open and later offer a retreat route to East Poland. What of course usually is against the rules.

Yes, I was thinking of that too. Does that also happen in other games like G40?

It never obivously occurred - as this has never been reported. But that is something to test now.

Tested with G40:

_2024-12-2-World-War-II-Global-1940-2nd-Edition.tsvg

So it does not happen in Global1940.

But I don’t know which core ruleset (old) Europe is based on codewise. So it might be that there are older core games where this issue has been incorrectly implemented.

I will start doing some tests recursively now. Maybe you can do some tests with older games, too.

Very strange. At the moment I am comparing the property lists of G40 and Europe, trying to see if there is any noteable difference there that might cause the issue.

@VictoryFirst

v3-v5 don’t show the issue, they work correctly. Now testing v2.

[VictoryFirst]

I tested with Classic and was able to reproduce the issue

Bug also occurs in classic.tsvg

So here the fighter from Mocsow attacked Eastern Europe through Ukraine which was captured in a battle that same turn, and the land units are able to retreat from Eastern Europe to Ukraine.

@VictoryFirst

And I tested v2 and the issue does not occur there.
So old Europe map is codewise based on v1 ruleset.
I am now going to check the retreat rules of v1.

[VictoryFirst]

Just checked Revised, no problems there.

[Panther]

@VictoryFirst Revised=v2

@VictoryFirst

OK, so the old Europe Map codewise is based on Classic (v1) rules. Here the retreat rule is as follows:

So the plane came from a territory that - at the time of retreating - is friendly (as it was captured before). The rules are different from other editions.

So engine-wise the behaviour is correct. The Europe map is codewise based on a ruleset that allows this special retrat move. It’s against the Europe rulebook however.

@Panther

Ah, that explains it. Thanks!

@VictoryFirst

It looks like the players - once again - have to take care of the game rules themselves. As v1 rules differ from the Europe 1999 -rulebook.
