Hi everyone, I'm running the simulation in open studio, but it fails. This is what is written in in the eplusout: Program Version,EnergyPlus, Version 8.5.0-c87e61b44b, YMD=2016.12.16 19:38,IDD_Version 8.5.0 * Warning * IP: Note -- Some missing fields have been filled with defaults.

It's written that there is an error in the weather file, in the 1st January 2050 at the hour 1. But if I open the .epw in Elements it seems everything is ok. Any suggestion? thank you
