This seems like a subtle rendering bug. Here is an even simpler case:
line = Table[{x, 1}, {x, 1, 10}];
line[[1, 2]] = 1.*^7;
Graphics[
{Point@line,
Line[line]},
AspectRatio -> 1/GoldenRatio,
PlotRange -> {0, 2},
Axes -> True]
Whether the line displays depends on the relation of the outlier to the max
Plot range. Decrease the outlier by a factor of 10 OR increase {0,2} to
{0,20} and the line will reappear.

Weird (bug?) behavior of PlotRange in ListPlot (Mathematica 7, WinXP).
Try the below evaluations in order:
Here are two {x,y} data series:
data = Table[Table[{4. i, RandomReal[]}, {i, 1, 18}], {2}];
ListPlot[data, Joined -> {False, True}, PlotRange -> {All, {0, 0.5}}]
So far, so good. Now replace the 1st point in the second data series
with a large-magnitude outlier:
data[[2, 1]] = {4., 1.*10^9};
ListPlot[data, Joined -> {False, True}, PlotRange -> {All, {0, 0.5}}]
What happened to the joined curve (2nd data series) -- it's gone!
But now change the "All" to "Full" in PlotRange:
ListPlot[data, Joined -> {False, True}, PlotRange -> {Full, {0, 0.5}}]
Everything's now okay - the joined curve is back!
