Hi Brauner and welcome to Subsim matey
Here are my suggestions ..
1. Stick the kettle on and then make a nice cup of tea/coffee/cocoa
or
2. Go round your Neighbours, wish them a Merry Christmas and beg/steal/borrow a bowl of sugar [see 1.]
or
3. Grab your T.V. remote and go up and down the T.V. channels until you realise the Gogglebox is producing tripe in the guise of entertainment.
In other words, it takes longer to load the Game, saved or otherwise because there is a lot more 'stuff' for your processor to sort thru.
Hope this helps and Merry Christmas.
