Like what sort of problem would occur?
For those who may have to log in in the wild, especially if hostile mobs are nearby when they do, they may lose their mount and pet due to having to put their clade gifts back together. Instead of being able to ride away or take defensive action.
Or they are overweight due to reduced attribute and skills, and the mount refuses to let them on, or throws them off when they get on. Again, if they are doing this in the wild with hostile mobs nearby, it can mean total loss.
Assuming that every player is aware of the clade reset when it happens, it can cause unexpected chaos and unnecessary unhappiness for those who weren't aware. Especially given how SV doesn't communicate very well at times.
A crafter could be logging in at the workbench, they assume that nothing has changed and they start crafting. Their crafted goods are suddenly lesser quality and they waste valuable mats. They could be doing this for quite some time before they realise that anything was wrong.
Best is if SV simply inserts a reset button so those of us who want a reset can do so without disrupting everyone server-wide.
