Yep.Had same problem.I've got ticket,also.As I got,while playing,info and structures to be packed into save file are getting massive-my savegames became 270mb from 170mb.This last one by the plane is getting even biger.And corrupted.

It's keeping corrapt savefiles.Autosave near the plane underwater.Kinda getting unplayable.Here is dump https://dropmefiles.com/620Gp

Hello.No it was something like 0x0000DEAD.I got corrupted savegame on cntinue after reloading game(today).So,it continue to corrupt saves after Miller got files from CSAT harbour base.And logically game shold overwright the oldest save file.But it is overwrighting the newest one.So,this all is kinda struggle with bugs.
