Cathedral is level 13 now

From 13 to 18, there's still a long way to go, but it's admirable how you're steadily building it up. With a clear goal, your patience will surely get you there, hmm!

I'm only level 11 now, I don't know when I'll reach 18 haha

You worked hard to level up your Cathedral to 13! It might not seem like much is left until your goal of level 18, but the resources and time required increase drastically in the later stages, making it quite challenging. Keep up the effort a little longer to reach level 18 and graduate cleanly. I'm cheering for you!

The road ahead is long. I also got a hidden quest in a building game, but I have to build it to level 20 and the deadline is 7 days. There's no solution.
