I think there is a bug on the test server with the Foul event item - in the normal provision house, I can create it with 7 bananas and 6 wet grass, but in the rarity provision house it's with 7 bananas and 9 wet grass.

1. Final reward from the calendar as decorative building? It is not a big achiev, so fine. Perhaps "generates 1 brew / 6 minutws w/o resources". Its a Cup afterall Just a tiny bonus.
2. Footie pitch - seems underwhelming ATM.
* Buff duration seems too short (6 ticks in natural population growth rate (+30), 1 in village schools (+5 per school) _or_15/7/5/2 ticks in Bronze / Iron / Steel / Damacene smiths. Nett gain +75 / 35 / 25 / 10 swords at smith lvl 5 per smith per day. Doesn't seem to affect bowmakers.
* Buff uptime 1.5h / 24h cooldown = 6.25%
* Maybe one day it will be upgradable (like schools) or new trainings arrive (like rarity provision).
* Consider a better use from short boost once per day, instead of negligible bonus to something, which is 24h up this way or another.
* Possible new recepies (more utility / synergy please): barracks, elite barracks and Expedition Barracjs training speed boost; provision and rarity provision speed boost; Bookbinder speed boost; faster general travel; faster general recovery; faster geologists searches for the duration of the buffs, extra building queue slot for the duration of the buf, etc.
* Plus, it looks weird with that guy standing for ages without ever shoting this ball
3. Friaries. With recent guild market offer... I guess most of players is set for live.
4. Two more very fast explorers with random buffs. Yes, please.
5. Hooligans at the centre of the island - Great idea!
If this event is as well done as the easter event this year, then it will be great. I just hope it is... as its not one of my favourite events to date.
