So I was able to continue the game over the point of the crash on may laptop
and than save the game. This gives me a save game that crashes upon loading.

journald tells says this at the time of the crash:
OpenGL dispatch[7562]: segfault at 0 ip 00007fef119622ce sp 00007fee95ffa368
error 6 in libc-2.23.so[7fef117f0000+1c0000]
