Rob has had a series of really bad luck.
First he went to Spain for his winter sejour from the Scottish winter where he and Les were duly robbed of all their personal stuff including passports making it really difficult.
On their return to the Alt they were met with a burst pipe and a flood that ruined virtually everything in the pub and their appartment. I have seen a video that Rob took and it nearly brought me to tears.
So at the moment they are living somewhere else while it all gets sorted, he has no internet there so hence not being on the Shed for a while.
I can't imagine how it's possible to cope with such adversity, I think I'd curl up and hide from it all, So lets send Rob and Les some good vibes.
