This is embarrassing. I've made it to Level 43 and have been unable to figure out how to put a territory link in a comment. I suspect it is a simple copy and paste but what the heck do I copy. Obviously, I'm an idiot so dumb your answer down as much as possible.

I just learned this last year too so no worries lol
in the chat you click the chain icon by the send button, then click territory in bonus you want linked in chat

use the chain/link icon and select the territory or bonus you want to link

if you are on PC, you can also use CTRL + [click on territory/bonus] if you have the chat open

A truly mind-blowing knowledge.

Thanks a bunch! As I have always suspected it is easy.
