Divide by zero error when calculating delay

[BeanBagKing]

As a note here, I didn't set a -Delay value, because it previously defaulted to 30 minutes, which was acceptable. It looks like that default is still there, if I'm reading the code correctly. However, when running the script, I received a divide by zero error and no delay. The error message is reproduced below, please let me know if there is any other information I can provide.

I just noticed a "ConvertLargeIntegerToInt64" error prior to this that may be part of the problem. I missed it earlier because I thought it was another "Cannot index into null array" error. I also received a null array error for line 347 (in addition to the two for 538 and 539) when running Get-DomainUserList.

Started a new spray and added -Delay 1860. I still recieved both the null array and the "ConvertLargeIntegerToInt64" error. It got to the point of "Are you sure you want to perform a password spray..." prompt. I hit yes and it displayed the "1 of XXXX users tested" and froze there. In other words, the "1" did not increment. After a minute I ctrl+c'ed that run, backed out the delay, and started again. Everything seemed to run fine.

Edit: Fixed this by adding $DomainEntry = [ADSI]$DomainEntry as the first entry in the Get-ObservationWindow function (now line 538). Not sure about the Null array errors. Still doing some testing.

Edit2: Inserting my own delay still seems to make it freeze on "1 of XXX users tested"

Edit3: Ok, the delay thing might have been my own misunderstanding. My assumption was that this was a customizable delay between each password spray. It looks like it's a delay between each individual account tested though.

I am running into this as well. Basically defaults to no wait between sprays. I tried adding $DomainEntry = [ADSI]$DomainEntry, but that didn't make a difference..
