Outpost uncapturable

[Langbart]

The following maps contain at least one outpost, that is not capturable. The template is called structures/palisades_outpost.

grep -r --include="*.xml" "palisades_outpost" . | uniq | cut -d: -f1
./skirmishes/forest_battle_4p.xml
./skirmishes/alpine_mountains_3p.xml

to reproduce

• Start one of the maps listed above.
• Try to capture the outpost.
• Check the icon, it shows a palisade and the health is much higher than standard outposts.
• See image below for more clarity.

expected behaviour

• The outpost should be capturable.
