comment Preventing complex term in a differential equation solution
Thanks. I used the code Table[{t, sol[t]}, {t, -4, 0, .25}] // TableForm and all the results were real numbers, whereas Table[{t, sol[t]}, {t, 0, 4, .25}] // TableForm generated all complex numbers and so did Table[{t, sol[t]}, {t, -8,-4, .25}] // TableForm. That's why my plot exists only on (-4,0).

This worked for me, so I do think we have discovered a bug.
