Did you warp to Uveto from New Texas somehow? Do you still have your Melee and Ranged weapons? If you use the
Cheat Menu to warp to New Texas to clear the flag, make sure you do it from a square that doesn't have the 'Bitterly Cold' effect, though you may have to warp back for your ship anyway.
Alternatively, you can open the console (F12 or Control + Shift + I) and type
pc.removeStatusEffect('Disarmed');
If you don't have your weapons
returnAllItems(true);
flags["CHECKED_GEAR_AT_OGGY"] = undefined;
This bug can't be fixed for others unless someone figures out how it happened.
