Confirmed on my end. Access violation.

However...

Code:

#17 {afflictions=%additem("confusion",@afflictions)}

then running 'test' alias does not produce the crash.

GeneralStonewall, is this a variable newly created in 3.19e, or is it a carryover from earlier versions? Also, the way you add it might be the problem, as well (not saying faulty scripting on your part, but it might be a command adding the afflictions incorrectly or something).

Confirmed here too, and am creating the variable by just pasting the XML above into the settings editor. So either the XML import is messing it up, or something else is wrong.

It's also one of those crashes that bypasses the crash dump, which points to an infinite loop. Almost like #DELITEM can't tell that there are not any more matching items to delete and just keeps going.

The key to this bug was the "sorted=true" flag. There was some serious problems with the code for deleting duplicate items from sorted lists.
