I've had issues on a server running this mod with the temperatures seeming to become bugged. It appears as though their temperature gets locked into a certain range with some people overheating and others freezing while in the same place in the same conditions (clothing, altitude, source blocks etc.) I'm not sure if this is just something on my end but I can't seem to resolve it, it does seem to eventually correct for each person but seems to take upwards of 30 days to do and someone else usually develops the issue during this time. I think logging out during the summer and logging back in during winter or vice versa may be the cause but I can't be sure.
