You know how they say
"the needs of the many outweigh the needs of the few"? Well, when I'm
"the few" and I'm writing the code, then
"the many" can get knotted 😲.
If I didn't allow this break then my IDRotF game's menu would have gone from a useable this:

...to an unuseable this:
Sure - I use lots more NPCs than other GMs (I'm pretty sure that I hold the record for the most NPCs in a single game), but I didn't want a change that would make
my life much worse.
Now my moaning is out the way... I don't think this is a concern anymore. The NPCs tag means that GMs no longer need a hundred NPC character sheets in their games. I've checked in a change that'll keep the characters with the players. It should be in the next release.
