The following was reported by Mark Watkins.
{{{
sage: E=EllipticCurve('389a')
sage: Lp = E.padic_lseries(3)
sage: Lp.series(4)
O(3^6) + O(3^3)*T + (2 + 2*3 + 2*3^2 + O(3^3))*T^2 + (2 + O(3^2))*T^3 +
(1 + 2*3 + O(3^3))*T^4 + O(T^5)
sage: Lp.series(5)
O(3^7) + O(3^4)*T + (2 + 2*3 + 2*3^2 + 3^3 + O(3^4))*T^2 + (2 +
O(3^3))*T^3 +
(1 + 2*3 + 2*3^2 + 2*3^3 + O(3^4))*T^4 + O(T^5)
}}}
Note that the term 2*3^2^ in T^4^ has appeared in the second computation.
