Auto attack disabled on in Nexus Blitz when killing wolves

This has happened in multiple games. When jungling I will no longer be able auto attack after killing the main/exploding wolf in jungle. Tryndamere has been the only melee champion I have really used in the jungle with Nexus Blitz, but losing auto attack on him is a real pain. I have tried turning off auto attack in menu, playing for a bit, then turning it back on without success. Has happened in multiple games across multiple days (i.e. is not limited to a single play session)
