Unfortunately this heist is now OVER
Sorry to those who were in the process of completing, just try and get to the next one faster.
Speaking purely personally, I spent (wasted, as it turns out) several hours yesterday trying to solve this. I thought it was a very good heist, and worth spending the time on, and I also wanted to get the extra free app that was advertised as the reward. However, I was prevented from progressing, as it turns out, by a bug - which I have to say is pretty frustrating. Then, a day later, after I've been told that the bug will be fixed, the heist is just announced as being over instead.
I do accept that it would obviously have been a good idea for me to do the heist sooner, but the fact is that (for whatever reason) I only spotted it yesterday, and I did it right away. I visit MacHeist very regularly, but somehow had failed to spot this thread until now. If I'd seen it sooner, I'd have done it sooner.
Anyway, that's life, but it's pretty annoying. This was a particularly good user heist, I thought - very well done. Clearly a lot of time and effort has been put into creating it, and that really shows. I'm just feeling pretty peeved (a) to have had it unplugged on me when I was just about to complete it, and (b) to have missed the loot.
So my suggestion for your upcoming second mission is that you set a time limit at the start and let people know what it is. "Finish by such-and-such a date or miss out." That's fair enough, and clearly there does have to be a limit on these things. It just isn't very funny to do most of a mission and then be denied the ending and the reward.
