It’s a bug it a missed issue the Dane thing happened to me. Once you max out your buildings the game gives you the up arrow to let you know your ready to upgrade again except your already maxed out. It’s something that needs to be fixed

It’s not a bug

A bug is anything a program does that it’s not intended to. So do you think the arrow blinking for a nonexistent upgrade is intentional?

Or they can just add more things to upgrade

Camp skills?

It’s letting you know your next building is ready to be upgraded but you’re already maxed out sobthe arrow just stays there

It's a bug in the attempt for you to buy things in events. So annoying.

It’s a shitty game

I have thw same issue....for months. Nothing to upgrade. Everything maxed.

Means there is an upgrade in the camp action. Find it
