Zombie are not attacking

[Outlaw2101]

Hello

I installed the SP Lingor map on 1.7.7.1. I edited the loot table to my liking, adding some more eastern weapons.

When I first play the mission, the zombies act as normal. They react to sight and sound and will hit me.

However when I save and exit and resume playing later, the zombies will react to gunfire, but will not be drawn by sight attack.

Any ideas anyone?
