30 (identically shaped) parts. Diewall with conical shaped interior. I go to work order creation, hit process and wait...

Processing:

1 Part = a couple seconds

2 Parts = a few more seconds

4 Parts =  quite a few seconds

7 Parts = maybe a minute?

If I process part 1 (identical to the other 29) with a quantity of 30... maybe a minute.

If I process all 30 parts (30x qty. 1) 24 hours later it still is "processing".

I've checked each of the 30 (identical) parts, processed individually without issue. 

Anyone else had similar issues, and know solutions?
