v1.01 hotfix

Following feedback from early players led to discovery of the following issues:

• Pets were extremely prone to tiredness, which caused pets to become exhausted when players assigned recommended levels of play and skill training. This was due to an ill-considered attempt by me to rework the fatigue system at the last second without proper testing.
• Pets would become overweight even when following a dietician-assigned diet.
• Pets would auto-train activities even if they were too young to do so.
• Pets would barely use their free time, even with high independence.

A hotfix has been applied.
