[Storming] The Temple of Nine Bells

I've started a Storming the Wizard's Tower game, which I think is turning into a genuine campaign. We're two sessions in, and everyone really likes it.

An AP of the first session is online here:

The lists and character types are online here:

(Neither is necessary to read, though, for purposes of this thread.)

The group in question is a large group (4-5 core players, plus 1-2 occasional visitors) that prefers mostly traditional games like D&D 3E and Savage Worlds. Because of the large number of people, some of whom are fairly new to role-playing, and the preference for games I don't enjoy as much, I don't always game with this group. But I like everyone involved, and it includes some good friends, so I'm pleased to find a game that pushes everyone's buttons in a good way.

I know Vince has said on his blog that the game has serious mechanical problems (and I look forward to the revision and published version), but the game in its current form worked well for us, so we plan to keep playing.

I do have some questions, however.

Maps

John's character (Imperial Magistrate Li) has childhood memory as a map. It came up in last night's game as the PCs were tracking a pair of hopping vampires over the sacred mountain. John asked if he could use his map, I asked how it fit, and he said that his uncle, the ex-pirate smuggler, took him to the haunted forest as a boy (which played into an earlier piece of color/backstory, so it was cool). I let him make a perception roll (plus one die for the map), and gave him some useful background info.

1. Is that childhood memory now "set" as being about the sacred mountain? Or can he use it again, and have a childhood memory about the something else in the future? This seems to make that particular map more limited than the others, which have more versatile uses.

2. Should he have gotten a bonus die for the map? Or was the map's benefit simply the thing letting him make the roll on the first place? (This came up again when another player used his legends & lore map to learn more about the monster they were chasing).

Using Tactical Features<Healing Combat Damage

One of the characters had a healing spell, which he used quite a bit, to good effect. (The players were all quite explicit about how much they liked the way magic works in the game).

I had also added some healing items to the gear list (healing herbs and dragonbone powder). I didn't think much about how they would work, but two players picked them and tried to use them, so I let them count themselves as healers (per the 'Healing During Adventures' rules), and gave them a bonus die for the effort.

Which resulted in really powerful healing, even more so than the spell. So that wasn't so good. Clearly the bonus die was overkill; I had a hard time distinguishing between "This thing gives you extra dice" and "This thing lets your character do something they couldn't do otherwise".

But should characters even be able to heal themselves up? I'm not sure.
