Guild Wars 2

I took the armor off in a previous mini-game.
Armor got stuck in my inventory and couldn’t re-equip it so I destroyed it.
Now I spawn without armor in these mini-games.

That is your PvP Armor, which is completely independant from your normal armor.
You can switch it in PvP mode (crossed swords at the top left)

Never mind, PvP Armorsmith has free stuff if you trashed yours

You can “buy” all armor/weapons from the vendors for free.
The only thing you really have to pay for in PvP is different skins.
