Thanks for the vid and details /u/Ultrabluex, we're currently investigating why some colors of XP Coins are not properly showing an XP reward or filling the XP bar while still counting as being collected.
We'll update our Trello card on this when we have more info.
To add to what EmptyTux said, thanks a bunch for the video and comment with the additional information. These types of posts help us a lot!
Thank you for reacting right away also thanks for fixing celebration cup i now have my pickaxe:3
Any time!
As an update for this thread, we are tracking collected XP Coins and will be rewarding any missing XP in the 12.10 update.
Thanks for everyone's help in tracking this down!
