Talk:Chrono Trigger/The Fated Hour

Frog's sidequest, groups of Sentries that drop Full Ethers
I was playing through the game and sparsely looking at the walkthrough so I don't miss anything important. The walkthrough says that when you enter the Northern Ruins in 600 A.D. you have to clear the left side of monsters. Concretely there are 3 groups of Sentries (one of 2, another of 2 and the last one of 4), each of them drops a Full Ether when defeated.

It states that they respawn when you leave the ruins and enter again so you can stock up on Full Ethers by defeating them several times, but I experienced differently. If you defeat all 3 groups of Sentries they do not respawn, the only way for them to respawn is to keep fighting the first group all the time; i.e. defeating the first group, getting out of the ruins and reentering and repeating.

Has anybody come across this? Can somebody else verify this so the walkthrough is updated?
