BreezeFeather I am only now realising that Toyhouse doesn't give me notifications of new forum posts :( I'm sorry for the late reply! So like Mercer said, some HTML and CSS properties are blacklisted on the Toyhouse website specifically, and I don't really have access to TH's blacklist so I can't really reliably implement the blacklisting. Maybe in the future I'll talk to cyan about blacklist stuff, in the meantime you'll have to double check the code on TH every once in a while to make sure it's working as intended!
