[Feature Request] Force "no objective recapture" for all Advance levels

[shiftycats]

Is your feature request related to a problem? Please describe.

• Advance maps generally flow better when defending team is not allowed to recapture lost objectives.
• Being able to enable/disable recaptures on each objective makes for inconsistent game rules, which can be confusing to players.

Describe the solution you'd like Add bAllowRecapture flag to game mode class that would globally enforce the rule.

Describe alternatives you've considered Endlessly arguing about whether objectives should be recapturable or not.
