Don't tell anyone, but I feared something like this may happen at some point, though I was hoping not at that level of patches...

The problem is very likely a timeout due to the amount of work it takes to parse the modifications xml file.
I'm not sure unzipping is enough, but it may at least help out.
As time goes on, I hope that replacing entire files will be the normality and that should reduce the amount of resources required to do the update. For the next releases we just have to remember that micro releases have to be smaller...

Sorry for the troubles ant59.
