Using the SignPicture mod with this mod seems to make embedded chat links from this mod get popped up in an external browser window.
Quote from user NightFang47: I figured out what the conflict is. For some reason the mod SignPicture is getting the url that this mod sends to chat and then just opening those pages. SignPicture does have to communicate with the internet to work but I have no idea why it thinks it should open the URLs for this mod and not Mr.Crayfish's which also sends a URL to chat. Very odd indeed.
