I just learn TODAY that guarding planets make the truce protection useless. I've been doing it for months, guarding a planet and using truce protection and I've never had an incident of them not working. Until today, that is.

Can there be a warning in the Calming amp's and Halcyon trap's descriptions that the truce is useless when guarding a planet?

I thought this was common knowledge? Yes, you can still be disabled by another player while guarding a planet, regardless of truced/pacifiied status, provided they target you directly from the planet screen. If, however, they go to Use Enemy Artifacts or Use Other Artifacts they must re-target you from the guard list because the game sends it back to the default PvP mechanism wherein the trucing is in effect. Note also that when guarding a planet, you can still be disabled even if your Disables Action Count is 0 or less. Here again, if they open the artifact screen, it goes back to default PvP mode.

Oh, that's odd. They disabled me but I wasn't aware they did it from a planet screen...none of my planets were attacked or invaded...weird (unless I'm being stupid here -_-)
