This is the first time I've tried (with Generations), so I'm not sure if it's something with Generations, or if this has happened to anyone before that EP came out. I click on the mailbox to "order omni plant seeds". The Sim goes to the mailbox and then just stands there while the action disappears from the queue. So, I only have the initial 3- 2 actually (I deleted the "horrifying quality" one of the 3), that I ordered when I finished with the opportunity.
So, does anyone have anything that may help? Thanks.
