When viewing the Collection screen within Troops & Teams page (Troops menu item,) the denominators for the total number of Pets and Team Slots appear incorrect.
Pets collection total -
On the Xbox, my collection displays 227/226, with no unowned pets shown in the pets screen [the platform exclusive pet (X-Ball) has not been purchased.] A quick check of the pets screen confirms ownership of 227 pets. At a minimum, factoring in the unowned platform exclusive pet, the total available pets, on the xbox, should be 228.
Team Slots total -
The maximum number of team slots displayed 46 [1 initial slot + 25 (1 every tenth level through level 250) + 20 (1 per VIP level)] has been incorrect since the introduction of warbands (currently five available, nine released warbands.) Assuming all the possible warband team slots are the only ones missing, the maximum total team slots should be 55. Perhaps the total is meant to only include the user purchased warbands, so the maximum could vary by user. This issue appears to be similar to the initial Banner total count not including warband banners, at their release.
Even the tip in the Team Slots>Slot Amount section of the official Troop menu and Filters overview webpage, shows 51 total available slots. This webpage appears to have been written post the release of the initial five warbands, but never updated with the subsequent release of two sets of two additional warbands.
Both these maximum counts have been incorrect for some time.
Editorial opinion: These maximum counts should be known to the developers of the software, to assure adequate index range and storage space.
