The frog leaps into the air, but never returns. It just keeps walking mid-air. I am no longer in combat.

P.S. I will just wait until the weekend so that they fix all the bugs and glitches.

Hello,
The frog did some jumping but he always returned - perhaps just keep fighting and staying on him. I did a lot of rolling - both towards and away - I used axii on him also which seemed to keep him still a short (real short) period of time. However, I am on Playstation 4 - not computer this time as my old computer could not run Witcher 3. I will be excited to get another computer some time in the future so I can play my DVD which I had already purchased. Maybe first day available had tons of people and things were slowed up.
Good luck with the toad. Hearts of Stone so far is fun and funny.
Rebooting is always a good idea also.
