[Bug] Caves do not provide shelter for devices

The bug where it rains inside caves is back again. Even worse, devices that have been built in caves show up at not sheltered despite being deep inside. I even built a wood roof over the devices which worked during the playthru but when I resumed the prospect they were unsheltered again. Removing a single roof tile and replacing it fixes it for that playthru. Clearly a bug. I've seen this happen at multiple cave locations. Most recently on the northernmost cave in the forest outpost.
