Playing the new version from scratch.  Error message in the house above Ari's house the day after we first arrive there.  In the basement while fighting the second rat (After looting the chest and equipping the boots and the ring from upstairs).  

Error

Uncaught TypeError: Cannot read property 'refresh' of undefined

At

LAMB_Map.js : 13

I went back and fought the rats again without looting the boots.  I fought the second rat (the one on the far left side) first and then the on on the right side second.  Right as I defeated the rat on the right side the same error message came up. 

Just to add its popping up in the zone above where Ari's house is as well.  Same error and it happens right after the second combat on a map. 

The error does not occur after accepting the cultist quest.  I was able to kill the rats without any problem after that. 

It's good that the new error messages are working as intended. I was able to find out more about this bug, it should be fixed in v1.10 which I'm uploading.
