I've just uploaded v1.10.0 of Chatmanager with all the necessary fixes in it.
One thing I decided to abandon (perhaps temporarily) is sending the link information in a way that the server could recognize in order to do its anti-spoofing check. Unfortunately that means you can still send a spoofed item link to someone, and if they try and send it on via normal means, they'll be the ones disconnected
. I'll keep on thinking about how best to solve that one, but I guess there's always going to be a hole in this logic, given you'll never know which version of Chatmanager is sending you those links on a private chat channel anyway. (Same problem with ChatLink as well BTW).
Anyway, enjoy!
