So after my game disappeared yesterday [again, again again] I tried a restore from my Recycle Bin and low and behold I'm back, the game is saving and progressing.
My picture shows some fallout: I have 8 [free] ZIKA 612H plus the new heavy crane. That being the last truck I was using on the PTS before the release of Ver 25.
And I have two of the new Bukka's Today I was able to restart that misson though it was already done, but today the game spawned a second vehicle for me to recover. So I hope the fix, obviously from Saber, holds.
Cheers.
