AI not being able to claim throne properly

[JackNotLantern]

Situation is as follows:

1. Christian country AI has an alliance and RM with another christian country.
2. Their ally has the same dynasty and no/weak heir.
3. AI claims throne, gets "Claim on the Throne" CB, becomes domineering torward the ally and break the aliance.

To this point everything seems as intended. AI is preparing for the succession war.

The issue is, to declare the war without -1 stab for having RM with the defender (or just because they stopped liking their former ally), the AI break the RM. This makes them lose 1 stab anyway for breaking RM, and lose the "Claim on the throne" CB.

So instead of succession war, the result is: broken alliance, -1 stab, loss of prestige and relations because of claiming the throne. The can't get a PU this way, unless the other side breaks the RM first - then they keep the claim.

Here is an example:

Spoiler: Example

France claims throne of Provance

France breaks the alliance with Provance because of domineering attitude

France breaks the RM

After 1 month France looses Claim on the Throne CB

Provance still doesn't have an heir - France breaking RM is the only reason for losing the claim

If Provance broke RM first, France would keep the claim.
