I have been putting my troll camp in storage after every collection since saturday. I have only had one collection since then where I didn't get troll extract (only in my second kingdom).
I'm not saying this is THE answer to the troll camp problems, but it certainly doesn't hurt to try.
I collect from troll camp, put it in storage, do something in my kingdom (like collect my wizard schools), get the troll camp back out of storage. Rince and repeat. This way you don't miss any collections (don't forget to take it back out
) and troll camp is only delayed for a few minutes.
I don't think I'm going on any more adventures, because they are definitely dissapointing. No troll extract there, so not worth my precious gold nuggets.
I need 15 more troll extract in 9 days. If everything keeps going like this, I might possibly finish this event (Oh, I completely forgot carnaval/fat tuesday/mardi gras, which will keep me busy for 3 days . Hopefully I manage to squeeze in my collections...).
