quest bugs

hi there!

I have two quests in my Quest Book which I cannot complete because I already did...
meaning,
the Missing Easter eggs quest, where I have to complete the Easter adventure "Lost Easter eggs", popped up after I actually already DID complete it - 3 times. so I now it doesn't recognize it.
and,
The bone discovery quest, tells me to find yet a stone deposit (and raise stone in stock by 100), but I already have five found deposits, so the geologist is not permitted to find any more...

hope someone has an answer...

happy playin' y'all,
KASPER
