I would like to make a suggestion for the menhir system.
Right now, when you menhir you lose fields but get back the resources in inventory, which makes it very easy to abuse of it. You literally have a farm with 400k resources ready to be taken at any moment.
To avoid this problem, could you please either:
1. Leave resource fields leveled up --> Either way it's just a question of timing to rebuild them, which can be done almost instantly for 100 gold or less
2. Make it so those resources are not raidable
The first option would be probably the easier one to implement.
It's very easy currently to abuse of this.
