Random Tasks?

You will always get a random task pop up, it's very rare not to have at least one especially when you have completed all your tasks in any questline.
During one questline yesterday I had three random tasks pop up, Milhouse fly the kite, grandpa telling war stories and Fat Tony digging a problem.

My task book is empty at the moment so i put all my characters on 24 hr jobs, if a random speech bubble pops up i just leave the character until i have finished assigning the jobs hit the millhouse/bart button then go back to my town and the speech bubble will be gone to put him/her on a 24hr task.

Theres nothing worse than all your characters on 24 hr jobs at the same time and 1 gets hit with a shop at the KEM task

I had been getting the random tasks before Halloween, but now I don't get them anymore.

I think it's because I've left a couple questlines incomplete for awhile now with Skinner and Agnes perpetually tied up on the open air stage. 8) Maybe I will free them soon and let Hans pick up the slack.

I only have 1 quest going right now. I have been getting random ones. Some of them are only 1 hour. Kind of annoying! I guess they don't like it when there are no tasks being done.
