if it isnt a complete set 14 levels 9 adventure 5 timed and 1 secret the playlist will show up in the arena community levels! i hope this helped!

But the thing says it has to have at least 3 levels to upload

yes so if it has 3 or more but not all go into local or multiplayer, arena, vs or coop, community levels: my subscriptions. It should be there if it doesnt have all fifteen levels. if its not you should probably submit a support ticket on the behemoth website

Ya its in my subscription but your saying I have to make ALL 15 levels in order for it to work or is there a way to make a small map pack?

well yes. you have to make all 9 adv 5 time and 1 secret for it to count as a Chapter.
however many people only make 5 or 6 levels and thats fine it just wont ever be chosen for furbottom features or be in the furbottom features community levels it will just be in the arena section unless you/they update it and complete all levels
so if your worried about it not being complete just take your time and finish them and them upload them and it will add the new levels and it will be complete!

Oh ok thanks for all your help

no problem!
