Hello,
after collecting first day's worth of bug reports I made a small patch addressing some of these:
Trade menu has been disabled (causing crashes)
Removed a corner case causing game to crash on load.
Charity pledge now works correctly and doesnt fail immediatelly.
Civilizations now correctly upgrade tiles to all improvement types.
Economy abilities that newly affect Predicaments now have more relevant 'bomb' icon.
Fixed a handful of typos, text overlaps and descriptions.
Cheers,
Ondrej
