I have installed the Carnival edition of Restaurant Story today as requested by the other games modules that I am playing.
Had a bit of problem initially but resolved this. Once the Carnivals edition was installed and working properly (this did not take long) I found that all my food that was cooking had gone off - which is a whole heap and the drinks and the counter with already cooked food was cleared.
I have the maximum amount of appliances and maybe a couple more and the restaurant was well stocked with food.
I am now cooking fresh food even though it did give the option to recover all the food for 16 gems.
Also since i have food as gifts that is initially supplying the restaurant until the new batch of food has completed.
I am just posting this in case anyone installing this edition can be aware that this could happen.
