Sometimes, in the late game, when there an unambiguous defeat on the next turn, bot simply presses the "End Turn" (in the future it may become the basis for concede).
UILog (UILogg_2015-07-09_10-37-43.txt) only describes the fights and this fight is not presence in the HB Log (Hearthbuddy 3308 2015-07-09 00.39.txt)(you attached the wrong file).
I don't see the skip turn in the UILogg_2015-07-09_10-37-43.txt, but I see another problem.
Open the UILogg_2015-07-09_10-37-43.txt using the
HSBCombatViewer, see step 15 and step 16 (steps 15-20 is your turn)
In step 15 you have the Knife Juggler, and in step 16 it just disappeared. Bot had to do the all calculations again.
It is very strange. If such situation is persists, please report it.
If you don't wish wait until the such situation is repeated, try to remove .net framework and visual c++ and reinstall its using the
Buddy Dependency Wizard.
