Night time lighting on Altis seems to be incorrectly set based on N. hemisphere seasons. Night time lighting appears to be darker in summer at 20h00 than it does in winter at 20h00 - same year - no clouds - same moon phase.
Since both Altis and Stratis are apparently in the N. hemisphere and geographically quite close they should have similar night time conditions baring a few clouds etc. Stratis night time lighting is imo perfect as it is.
