My copy is showing v 1.13.16.0, modified 16 Feb, and Update has no effect.
I manually reversed the flap modifications before I tried to update but I thought the hotfix actually had other items in it.
Tried starting the sim through the usual “Checking for Updates” but nothing happened. The Content Manager had an update for Orbx London City Scenery pack which downloaded okay and modified the version number, but everything else shows “Up-to-Date”
Not really bothered but wondering why?
