Hello, saving freezes after turn 150, 151 to be precise.

Neither autosave or regular save, wether on cloud or physical works.

Even after going back to previous saves and advancing until turn 151, the game (not the UI) still freezes on saving process.

It used to happen a lot on previous versions from back in january 2018, no thread about that topic seem to exist afterwards but the problem apparently still happens.

No mods used, playing on normal speed with custom faction, playing colossal size 4k with all graphic upgrades. 

Intel 8700k with 2080ti and a lot of RAM and Samsung evo SSD drive.

I tried rolling back to beta versions, lowering specs, try sautosaving from various screens no chance there...

Please help !

You should upload diagnostics files that log what happens when you try to save and it hangs.
