Planets can generate some of their own heat through gravitational flexing of the core causing frictional heat (the two relatively close moons would do this a LOT). It could also have a large fraction of radioactive materials in the core, which would also generate a lot of heat. If the atmospheric chemistry is right, it could trap quite a bit of that. I think the developers were smart enough to know that they were making an exploration game rather than a planetary physics simulator. I would not call it an oversight because there are too many deliberate unknowns.
