Uninstall Of Train Sim 2018

Recently my computer updated itself, however when the update finished and I went on to steam I found that Train Sim had uninstalled. It now requires me to do a full reinstall. I was wondering if anyone else has had this problem and if so how they got around it.

Thanks in advance

 

You are the first with that unique situation never had that happen to me.

 

I keep my W10 system up to date. I've seen my share of Windows 10 updates, but I can't imagine how Microsoft's engineers would know to uninstall a game from Steam. I'm thinking something else happened, maybe Steam update?

 

More than likely there is a dependent system that's been updated rather than steam or trainsim itself. Try a repair of trainsim before reinstalling

 

I had a similar issue but I got the option to repair it, it did download a few files but then it was working as it normally does.
