Running 1.0.0.26 on Win10 x64. Never had any crashes before this, and this is well into the current game.
I got a Scout unit in NW Maikop. It's linked to an Inquisitor. I felt like upgrading it before walking through unknown territory. That action crashes the game every time.
Tried upgrading a different Scout (Hong Kong). Upgrades fine.
Tried unlinking from the Inquisitor. Crashes game.
Tried getting Open Borders with neighboring civ, seeing as my linked units were trapped otherwise (I had OB right before this turn), then upgrading. Worked.
