Did you leave you sub alone? I'm on vacation right now for 10 days. I had to leave my EP500 home alone, but with friendly 60s' 150 and 8s'. I talked to them all and told them that even though they had just arrived I had to leave for a few days. I didn't say "vacation", but that we were going to a wedding. I gave them a full workout with "Master and Commander" and promised some "Das Boot" and "U571" on my return. Hopefully they will be ok.
