Question xp'

It seems like this new system is only giving 1 xp a day. Or is something not working corretly.  I also have potty use set at the 12 hr range but still have to go every hour ? Usng a lot of potty paper and soap. and no xp points.

If you have metabolism at Low then I'm not sure why the 'Bladder' gets high so quickly for you. For me it's taking about 2 hours to get to around 45%.  Will have a think...

what about xp 1 a day or less?

It all depends on how many hours, As an example this is my activity over last few days:
Sunday - 18:30 to 21:30 [3 hours]
Monday - 10:33 to 12:40 [2 hours], then 14:55 to 19:51 [5 hours], then 22:02 to 23:32 (1.5 hours)  
Wednesday - Came into world at 12:20 and it gave me the 1 XP at 12:45 which is correct, since I spent 3 hours on Sunday and 8.5 hours on Monday and the final 0.5 hour today before getting the point.

If you are thinking about the points for visiting Lugo & Mintor, they were one-off tasks.

Ok so if I set metabolism to high do I get 1 xp every 7.5 hours or still 12 hour until one reachs next level an how many points does it take to get points for actual tasks?

Setting it to Medium will give 1 XP for every total of 7.5 hours in world (High will give a point every 4.5 hours) At the moment, once you get to the next rank level, XP from just time in world will stop. Tasks give 5 XP for each one completed, although currently there are only the two visit ones.
