The file of solutions from (ai)remlf90 is formatted with fixed width, leaving only four spaces between the column of trait and the column of effect. Thus, if for one trait one has more than 999 effects the two columns become one.
Although it is not very common to have more than 999 effects, it is not that rare to use a splines component with, say $30 x 30$ knots (which gives $32^2 = 1024$ effects).
This is a weakness of the format, and we will ask for a solution upstream.
But it is convenient to write a workaround for that.
