no, a lot of those 'Fight boss' or 'beat X grunts' tasks need to be done manually. Skip battle won't register the task as complete.

try agent damage boost for group bosses

agent damage boost works for those cal in a friend things, where another agent comes by and attacks

Yea I didn't attempt it, I'll do it up until the Epic, then I'll just do the experience farming for the remainder of spec ops, I got a bit to do since they just released another hero today.

still working 4 me today ans ysterday too

I'm using Waterfox and UC Browser

Do you know how to edit xml files.  It is a good thing to know how to do, so you can make a new one.  Every now and then when they do updates old xml files no longer work.  Yesterday I had to make a new daily client.xml, so I can do 5 star in 1 run.

Not much, but on the GroupBoss, you can lower the 5% requirement for a LB.  (This is helpful if you're having trouble breaking 5%, if your GB starts with 5% or less, or if your Hero  - ie: QS - is doing too much damage to get the LB reward).
  > In client, search for Dracula, make sure to find the GB one (should be around line 8000).  Change from 5 to 1.

Here's what I've tried so far on the GB and lockboxes.  If anyone can come up with alternate methods, I'm happy to collaborate.

1. Changed drops to guaranteed U-ISO.
     Result: Success (see previous posts from other users).
2. Increased GB's total health to return a crapload of silver.
     Result:  Success (see previous posts/threads).
3. Increased Hero damage to defeat GB quickly.
     Result:  Success (see previous posts/threads).
4. Decreased 5% Milestone to 1% (see above).
     Result:  Success.  Fail (temporary success - you still need to take off 5% or more to actually get a LB.  Sorry!)
5. Changed 5% Milestone reward from 1 LB to: 3-50 LB.
     Result: Fail. (Temporary success, but doesn't stay after refresh).
6. Changed drops to guaranteed: LB, comic cover
     Result: Drops successful, but ends up as a Fail (CVE).
7. Changed LB map rewards from 10LB/1LB to 3-50 LB.
     Result: Fail (does not recognize change, still returns 10/1).
8. Changed Victory loot table to return 5 LB every time (instead of 1 or 3)
     Result: Fail (does not recognize change, still returns random amount).
9. Changed the random loot when redeeming 1 LB to return a guaranteed unique cover (this would have allowed you to collect the LB Hero by opening a max of 8 LBs).
     Result: Fail (does not recognize change, still returns random loot).
10. Changed weights in various tables to return a guaranteed item (LB, cover, etc.)
      Result: Fail (does not recognize change, still returns random items).
11. Change comic cover IDs in the comic cover loot table to return a specific cover (this would have allowed you to collect the LB Hero by opening a max of 80 LBs - 10 at a time).
      Result:  Untested. I may try this after the Spec Ops is over and I start to get desparate; I didn't want to waste gold on a theory because it requires editing items0.xml, and those changes don't seem to get recognized.

What other methods have you guys tried?
