fly, that is one of the items that is not completely rescripted yet. Anything in the images forum market item category is not working yet.
Also, I found a pretty moderate bug that was missed for the first 3 alphas that I consider important related to expirations. You can wait for the next alpha or you can do the fix yourself.
If you want to do the fix, open pointmarket/market_purchase.php
FIND
PHP Code:
$expire = ($getitem[expire]*86400)+time();
Change to
PHP Code:
$expire = ($itembuy[expire]*86400)+time();
I was referencing the wrong array. This bug caused any purchases to automatically be marked as expired within 24 hours.
