Pretty much what the title says; I'm on my 50 THM a lot doing lvl 40 leves for gil, so I'm often one-hit KO'ing monsters with spells. However, for some reason, if I'm not in combat, and I cast a spell on a monster that kills it instantly, it takes about 20-30 seconds before the game realizes I'm not still in combat, compared with the instantaneous recognition if I don't OHKO it. It makes it kind of a pain when you want to summon your chocobo/goober but can't for 20-30 seconds.
