Mac 1.0.5 Fight against Yseros crashes game

Hi everyone. When I enter the Gate of Gods for Yseros and start the battle, I will see the “Yseros has appeared” text, but once I hit “E” to proceed the game closes.

The error produced is “SiralimUltimate quit unexpectedly.” The detailed report is too long to paste in the post here, so I have created a Doc for it: Siralim Error - Google Docs
