Cannot “Watch the Train Demonstration” After Update

Found after update No train viewing in quest park. At first it works but after time it's reset with a sign saying you can't go. Just lost money. Can't break quest.

Having the same issue. Just tried to spend 14 life points to finish the train viewing and that got taken out but the task didn’t get completed. 

Me too! I tried using 14 Life Points and it still won’t let me start the task. 

I am currently doing the Simtown Express discovery quest but am getting stuck on the ‘watch train demonstration’ task. The task is glitching. I have done the task several times but it doesn’t let me continue/register it as completed. 
I updated my game yesterday which I guess could have caused the glitch.

Any help is appreciated.

Same here what do I do

Same, i have tried using lps but to no avail. Maybe a glitch 

I have the same problem, tried with every aged sims, and LP’s But nothing :(

Same here!!! I can’t go on with the other missions because of this glitch, what can I do??

I can't watch a train test. I can't watch a train test in the park. I have to solve this quickly to make another request, but I'm really annoyed

Same in my small town.

After starting the task, I left the park and only turned back, when the picture in sim tracker was flashing. Patience didn’t pay off, the task still didn’t complete.
