Considered him making ais offline.
Then once online itll start saving but he pressed server data.
(Sync errors are fixed 6.0 havent got one so far)
How i deal with this.(ive lost 14 ais cuz of this)(with other issues too, but they're kinda fixed)
I make ais offline- to save battery and just semi test them on training or sometimes, solo missions.
Every once in a while, because I got anxious about things, (like changes doest save when crashed cuz of complex stuff)
I restart the game everytime i make changes.( quit and play)
In this way i found out that it really helps me dealing with this stuff.
Then once im done,
Going online, expecting data sync error. (Always press local)
Then I play one solo mission with the newly made stuff, to secure everything.
Edit: crashes usually happens with wifi(online)as you apply changes to tge game.(keep local data doesnt really help this)
-(keep local data; resumes the last data from the last time you exit the game. Not the actual time youre playing the game and it crashed, as i observed.)
Edit: i just lost an hour of hardwork cuz
