There seems to be a memory leak somewhere. After something like 4-5 days with several loaded games and many searches the I get the waring the MacOS has run out of application memory. In the list FMRTE was consuming over 90GB of RAM. This has happened twice so far.  I can also see that the RAM usage is going up quite quickly while using the program and it does not reset when I load a new game.  It's not that critical. Just restarting FMRTE solves the problem for another couple of days and
