I'm running Imperium Universalis on a Mac. Whenever I try to click on either of the Punic War bookmarks on the date selection screen, the game crashes.

To reproduce:

1. On a Mac, load up the game in 1.34.5 with just the Imperium Universalis Mod.
2. Hit "Single Player", and on the date/nation selection screen, select the 1st Punic War or 2nd Punic War bookmarks. (In addition, just moving the date forward past sometime in 478 causes this too.) The game should then crash.

Some notes:

The game.log, error.log, and crash folder are available here.

I can confirm it occurs on both 1.34.5 and 1.35.

Testing it out by messing with the date sliders, the game works fine on the date selection screen on 1/1/478, but crashes on 1/1/479. (EDIT: After messing around some more, it works on 12/31/478, too, but crashes on 1/1/479.)
