Evoware crashes during worklist execution

Hello!
I’ve faced strange problem. We have generated worklist like
A
D
D
D
W
A
D
D
D
A
D
D
W
A
D
D
D
W
1st, and 3rd tip aspirates once, while 2nd does it twice, without changing DiTi.
Everything is ok, before I check “TAG after each dispense” in LC.
Once I did so, Evoware crashes right before second aspiration with 2nd tip.

Hi I don’t know why you get an error, I have only tried making multi-dispense like this:

Maybe you could see how this works if it is not too much trouble.

Thanks!
Already solved.
The possible solution is forcing liquid class without TAG in last dispense like this
A;
D;
D;
D;…LC;
A;
D;
