When I try to install FlightGear from TW :

mio:~ # zypper in FlightGear
Loading repository data...
Reading installed packages...
Resolving package dependencies...

Problem: nothing provides 'libSimGearCore.so.2020.3.13()(64bit)' needed by the
to be installed FlightGear-2020.3.13-1.5.x86_64
 Solution 1: do not install FlightGear-2020.3.13-1.5.x86_64
 Solution 2: break FlightGear-2020.3.13-1.5.x86_64 by ignoring some of its
dependencies


mio:~ # tumbleweed status 
latest   : 20221128
target   : 20221128
installed: 20221128


Closer inspection (zypper se -s) tells me, FlightGear-data and libSimGearCore
have been updated to 2020.3.17 but FlightGear itself hasn't.
