Scenario:
Join a party with members of mixed factions.
Party members allow each other base control.
One of the party members if a faction leader.
Two players, one of each faction, create land claims side by side and upgrade them so that they border each other with no buffer or even overlap.
Faction leader turns land claim of his faction member into a faction land claim.
The land claim of the non-faction party member is lost, now part of the other faction and unable to be maintained by the original owner.
TL;DR: if bases touch each other, a faction leader can claim both bases even if the bases arent owned by the same faction, as long as those people are in the same party.
