Auto fight not working

PDB

Once again, my auto fight did not work last night, yet used AP.  I set it up for a full run and woke up to find nothing happened.

This has happened multiple times now...no telling how many bouts of 112 AP I have wasted due to this persistent bug.

Hi,PDB,Our official staff made lots of tests and confirmation, in normal operations it will not cause the problem.   Anyone operation as follows will cause the problem.
1. Open the alts at the same time.
2. Use plug-in
3. Digress from the main game frame, operate in a new tab.

Please make sure you not do any operation above.

Plz tell me when did you fight the Laucs Soldier. After we confirmed we will give the ap you lost to you.

For this level and my last level, I have always done the same mob for autofighting.  Most of the time it works, but at least twice on that specific mob, it has not.
1. Open the alts at the same time. - I always have an alt opened at same time
2. Use plug - no plugins
3. Digress from the main game frame, operate in a new tab. - I have always, since starting, switched back and forth between tabs.  Many times, I don't care what is going on while fighting monsters, so I will check news, check on alt or some such

Autofighting, given the exact same circumstances and setup from previously, worked for last night

Hi, PDB, so please do not open alt at the same time, it will cause the problem. For the Ap you lost we will give it to you when your ap bar has room for it.

Thank you GM Fish, I'll keep that in mind about having alt opened at same time in the future!
