OR YOU CAN DO THIS!
When all of your links are not completed "https://apps.facebook.com/farmtown/claim_bonus/" or "https://apps.facebook.com/farmtown/send_ingredients/It appears that most broken links are due to being posted on other groups first and then copied and pasted elsewhere. Therefore to avoid this from happening it is recommended if you are posting on multiple FB pages in different groups BEFORE you click on "POST" copy your entire "POST" with all of your links etc, then you are able to continue pasting/posting in multiple groups without the broken links....If you forget and click "POST" you can always click on "EDIT" and then copy the links....or you can copy and paste them into a word doc, then paste them all onto a group wall. Unfortunately this is the NEW Facebook we can thank for this.
