I have an idf file I created and used in energyplus 8.8 but when I switched to 8.9 and updated the 8.8 idf file the simulation just crashes. Normally I would have the error file to work with to fix my idf file but this crash leaves me little clue as to what is wrong. I tried running the 8.8 idf file in EP8.8 again and it works there, with no errors. I compared the 8.8 and 8.9 idf files in the idf editor and there are no differences, meaning the update of the file seems ok. I suppose the new EP does not like something about my idf setup which was previously fine.
I ran the simulation with the "pause" function and at the end of the simulation I get this:

What could the problem be?
