"You paid 1 credits"

[Amazinite]

Should be "1 credit".

Combination of rounding and formatting, I think.

Fractional values are plural (e.g. 1.05 minutes), but the formatter will round credits to whole values. The string is built using the raw value, not the formatted value.
Nope:

endless-sky/source/Account.cpp

Lines 208 to 227 in 3dcd425

	out << "You paid ";
	// If you made payments of all three types, the punctuation needs to
	// include commas, so just handle that separately here.
	if(salariesPaid && mortgagesPaid && finesPaid)
	out << Format::Credits(salariesPaid) << " credits in crew salaries, " << Format::Credits(mortgagesPaid)
	<< " in mortgages, and " << Format::Credits(finesPaid) << " in fines.";
	else
	{
	if(salariesPaid)
	out << Format::Credits(salariesPaid) << ((mortgagesPaid || finesPaid) ?
	" credits in crew salaries and " : " credits in crew salaries.");
	if(mortgagesPaid)
	out << Format::Credits(mortgagesPaid) << (salariesPaid ? " " : " credits ")
	<< (finesPaid ? "in mortgage payments and " : "in mortgage payments.");
	if(finesPaid)
	out << Format::Credits(finesPaid) << ((salariesPaid || mortgagesPaid) ?
	" in fines." : " credits in fines.");
	}
	return out.str();

Checks for single-credit payment just haven't been added in this section.

So the desired strings are like:

"You paid 1 credit in mortgage payments and 1,234 in fines."
"You paid 1 credit in fines."

or are we also wanting to insert the plural credits before fines:

"You paid 1 credit in mortgage payments and 1,234 credits in fines."

Current behavior is for credits to only appear once in the payment message.

(Crew salaries can only be 0 or >= 100 credits)
