[srockw]

this happens because Menthol calls in_pool outside of a run, I don't know if that's meant to happen in general within the game

[wingedcatgirl]

Yeah I've been looking at the traceback, it's due to our mod pack booster trying to weight mods by amount of content. I don't immediately see a reason why this would be needed outside a game, but I do think in_pool is called outside of games some other ways, so a nil check here still seems like a good idea.
