Just noticed that my game version is now 1.1.4.2394.
Trainer options F1, F2 and F3 all result in "Please wait...Failed"
My two starting characters both died in the first battle.
Will be submitting an update request...

I tested all three of those options just now--on a save from a year ago and on a brand new game--and they seem to work fine.
Note the I'm playing the Steam version, which matches the most recent trainer version.
