Searching the bug thread is an exercise in futility. Is there a known issue with geysers, fumaroles, gas vents etc etc sometimes not appearing? I do a lot of tourism stuff, and most of the time the views are spectacular, but every now and then there's absolutely nothing anywhere in the vicinity of the tourist beacon. I've tried logging off/on and jumping out and back, but it doesn't help. I'm not sure if it's a (known) bug or just something that sometimes happens.
