I seem to be experiencing an aging problem with the latest version of AwesomeMod. I wanted to point this out because other users seem to have dismissed it as an Eaxian problem, but I don't have it without AM or with an older version of AM.
Basically, when I place a new family, they're almost totally done with their current ages instead of being near the beginning. Adults have about 17 days left (and I set it at 60), young adults have 0 (also set to 60) and indeed will age up the next day.
I do not have this problem with the un-modded game. Unmodded, it still starts a few days into the life stage, but only 2 or 3 so it doesn't bother me, whereas with AM it is almost completely done upon starting. It should be noted that the 10/19/11 8:09AM version of AM does not cause this problem for me. That version had no CTD issues for me, and no aging problems. Unfortunately, it had the bug of pet motives dropping in about 2 seconds, so I had to install the most recent one which seems stable in every way except for the age issue.
I don't know what exactly is causing this but how bad the bug is seems to vary depending upon the age lengths you set. Specifically, it seems like somehow the game is reading the % along the bar that you are, rather than the number of days you set. Here's what I mean:
When I select long sim lifespan and max all the bars out, as in Figure A, I get more days than when I set the sliders like in Figure B, despite the fact that Figure B is set to be more days than Figure A is.
When set like in Figure A, my adults start with around 37 days and young adults start with similar. Not terrible considering I only asked for 45.
But when I select epic sim lifespan and set my ideal numbers, as seen in Figure B, my adults start with around 17 days and my young adults start with 0! Which is pretty terrible considering what I tried to set it to. So I don't know if this makes sense from a programming standpoint, but it seems like somehow lifespans are determined by how maxed out the life bars are, rather than by the actual number of days you set.
When I max out epic lifespan, it is also not perfect but closer, giving me several 100 days, just not the full amount. It's not game breaking but it is pretty frustrating that right now I can only play with less than 45 days or more than 180 and nothing in between.
