Hello,
I´m afraid I´d had a similar bug. I´ll try to explain it the best as possible.
After have done about 12 or 13 terror missions, I had one in venezuela or someplace like that (but it wasn´t in the rain forest, it was a small town with buildings). When I finished that mission, it appeared two phrases (``sentence<......>TODO´´ , sorry I don´t remember them well) in lieu of the text I suppose there must be, and in the bottom right corner a smaller phrase: ``click to continue´´. I clicked there and in every place of the screen but nothing happened. I tried that mission a second time and it was the same.
So, I thought about not doing that mission but the aliens kill people each certain time because the terror missions don´t dissapear (I don´t think that is a bug). After some time it appeared other terror mission and I tried to get there with the thunderbird (the plane which carries soldiers) and UFOs destroyed it always in the route to the mission :S. Maybe that´s also normal but I wasn´t keen to continue trying playing with the permanent terror mission in Venezuela I couldn´t solve (and with all the governments getting angry
)
PD:Sorry for my English.
