Until SC has a chance to correct it, food appears to be required to rest everywhere. This is a temporary issue.
In the meantime, I've placed food in the starting area/inns. Please take only what you need.
Well, now I am unable to rest anywhere in the wilds. I ven tried in a place titled "Lair" with a bedroll, campfire, no enemies in the map, and food and not having rested in a few irl hours, with no luck.
Resting in the Kua Toa inn took HP away.
Pereppi was unhurt, and woke up with -38 magical damage.
