Could you please zip the save before this crash, upload it here (you can attach a zip file to a post) and describe the steps needed to reproduce this crash? We can't reproduce it, units are moving normally over Loki traps in the current version. Thanks!

Here you go:

Beat him with your saved game using 3-4 summoned demon stacks via demonologist (long battle) and ancient phoenix.

Executioners ran into the fiery hexes about 3 times, no crash.

I even intentionally ran an ancient phoenix into the fiery hex, no crash. His own units ran into the fiery, no crash.

Even beat him no loss, no crash.

Can you describe the procedure to crash? I'm using build 6250, did not change your gear, just went to fight Loki immediately upon load.

Get crashed again and again (build 6450), until I changed the combat speed to "Normal"

Got indeed the speed at fast.

@ckdamascus didnt change anything, that save is the way i went into the fight.

However the game crashes sometimes also in other fights too. useally with the loki rage skill and the golem rage skill.

I always play on fast animations.

Loki Rage crashing is symptomatic of the old versions of the game.

I'm really curious if you tried casting Pygmy, what the enemy HP would be.

Also, I'm curious if Avenging Angel is broken for you or not.

Or perhaps you didn't delete every file except the .kfs files in sessions/addons (2 of them) and a locations directory.

Last modified date time for loc_ses.kfs and ses.kfs is going to be around 12/6/2012.
