prevent oshan hotspots from spawning directly under the station

[Mopcat]

it's never fun when you're on oshan (which we have been a lot recently) and the game decides that spawning 2-3 hotspots directly underneath the station is a great idea. moving them is an arcane art that can only be correctly performed by those gifted by the great sages of crungledon, so it more or less is just a permanent problem that destroys your department and makes it uninhabitable within the first 15 minutes. please just... stop them from spawning right under the station. i thought they couldn't before, as i've only seen this happen recently, but apparently it very much can happen and it sucks please save oshan
