Edit

I tried it on "Charles De Gaulle 1939" and "World War II Global 1940 2nd Edition" and got the same behavior. You can't click "OK" and play through it. The error will continue to pop up.

@zemjak I think this is caused by your change #12084.

Looks like contrary to our discussion, a null check was needed.
It seems purchase gets set to new IntegerMap<>(); before that code runs, so assigning null to it isn't correct.

Can you take a look?

[zemjak]

yeah, could u assign me?

#12141 fixes this. Pre 14586 works correctly
